grayscale grid color changing

Hello

I need to make this simulation probe network nodes of energy levels. As the energy of node decreases its corresponding place on the grid changes color. I would like to draw each node on a grid defined by the values X and Y of the node. I want also graphically color each node in grey - scale, so that the energy value lowers the dims of color. I have attached the representation of nodes on a grid of gray scale. How can I draw the grid and how can I periodically change its color that changes of the energy values.

Please, provide me the starting point and indices

thanking you in advance

Something like this:

You can replace the constant table 2D with your data file. I supposed that X, Y, Z (energy).

  • Background color changes when you save a theme

    Just did a new install of Windows 7 Home Premium and has found that, when I save a theme, the background color changes from black (what it was worth) to white. Another thing to note is that when I save the generic theme "Custom Theme" (meaning an unsaved theme) remains, and the background color in the registered theme is changed and does not change when I click on the "custom theme". This is a new installation, so the only software that has been installed is video drivers, network cards drivers, the drivers of the antivirus and sounds. I've used the System File Checker, and he found no problem.

    If you are tweening text, select the text > click Modify > break is > change > to break.

    then, you can tween the text (which is converted into forms twice using 'split').

  • Color changes during the recording of the PSD to JPEG

    Any help would be appreciated

    Just to be absolutely clear on this point - the problem here is that the file is in ProPhoto RGB.

    Windows 'Photos' isn't the color management and cannot represent a ProPhoto file correctly. No more than any other application without color management.

    Convert sRGB. It is the right answer to your question (which is the error of the very common beginner, BTW).

    In Photoshop, go to Edition > convert to profile > sRGB IEC61966 - 2.1.

    If you're Using "export as" or "Save for Web", just check the box convert to sRGB.

  • Except for the color change of the Web of gifs

    I'm trying to 'save for web' a gif, and I get a change of color each time. I changed my color settings so that it is set to RGB monitor and it is extracted under test format as well. On the Save for Web window, making sure that "Convert to sRGB" is checked as well.

    Despite all this, the color change always happens. Here is a screenshot of my color settings:

    Screen Shot 2016-07-19 at 10.48.33 AM.png

    Is there something I can do to fix this? Thank you in advance!

    Saving as a gif you are inevitably reduce your color up to 256 colors gamet and so according to your original image you can result in a change of color simply by there. You must however not use your display profile in your color settings. If you want to put something on the web or in an application that is not color has managed the best choice is sRGB. Try these settings.

  • Color change bridge > Photoshop

    When I open a jpg file in photoshop, make the alternations of color, then click done and actually opened it in photoshop the colors change, I'm editing for the use of the screen, so I select proof of installation > RGB monitor, which is the reason why they change. However anyway is to see this 'mode' while doing the alterations of color?

    This isn't a situation where you would use proof - is planned for the overview of printer profiles.

    As far as I know, proof Setup > monitor rgb disables color management, and is not something you want to do.

    If your work is planned for a display screen, make sure that the sRGB profile is built-in when you save the image.

  • Color change in the exported sequence (Premiere Pro)

    Short description: colors in exported from first and downloaded movies on YouTube do not match the colors of the source that were imported in the firstimages.


    Background: I use tool of digital color meter from Apple to read the colors on my poster and Apple Preview to display image (PNG) files.  To eliminate the effect of color profiles, I put my 'Generic RGB profile' poster (which, as far as I know, does not change the R:G:B values).

    Description: I made a sample consisting of a single color animation and exported an image as image file.  Such color as displayed in my animation software, that's what I've specified (R:G:B): 255:0:255, as it is in the exported image as seen in Premiere Pro.  However, if I export a MOV file in Premiere Pro, upload that file to YouTube and play, the color is: 251:0:254.  Also, if I open the MOV file in QuickTime Player and export an image, the color in this context is 251:0:254.

    Question: what causes this color change, and how can I eliminate it?


    N.B.: This isn't 'gamma changeQuickTime Player' (at length elsewhere).  The color as read in QuickTime Player is 242:13:207 - a large and easily visible difference and who does not appear in other players MOV (ex: Player Flip).

    I JUST DISCOVERED SOMETHING!

    I was testing my single color sample. MOV file on different browsers, and I noticed that he had a slight color change between when YouTube first loaded (Chrome browser) video and when he played.  When I stopped it at the first point loading and read the value of the color, is 255:0:255 - just what I wanted.

    I now believe that the video I'm generating is correct and YouTube does not alter the video as part of the Uploader, but it changes in reading it.

    So, I'm done.

  • Colors changing when you export files HAVE in InDesign

    Hello

    Since the upgrade of CS6 CC last year, I think my profiles color or something are put in place bad between CS programs. When I'm working on a file in Illustrator (RGB) and then place it in indesign, as soon as I export the PDF the colors change. For example, a series of gray tones will be released as blue and bright orange. I'm not clued up with the settings of all programs and the inner workings, but I've never had this problem before, I've never had to change all the color settings, so think, need a new default setting I don't know.

    I understand there are a many settings that could do that. I export the PDF RGB file too, but I can't see a likely switch to CMYK. Is anyway to reset all the settings back by default so that I can at least try and get the settings I usually use with CS6.

    Don't know what to do... any advice would be much appreciated! Thanks in advance

    Your Illustrator color settings is a problem. Choose 2 North America prepress of the parameters, which will assign sRGB to new documents and allow you to assign a profile to the existing docs. You can also consider to synchronize all your Adobe applications through the bridge Edit > color settings.

    As test try to synchronize your color for North American prepress settings, create a new document, place the file I and export with the output parameters in my first post.

  • color change

    Now and then my color space seems to change on its own, and I can't figure out how to recover from the previous color space.

    The last time that happened, I was 'save for web' and that he was trying different settings of sRGB checked and unchecked. This might have caused the problem, but I do not know why because it is not the color of the recorded image which is at issue. It is the color space of the PSD file that has changed somewhat. The change is that the colours are duller and seem more washed out.

    I know that this has happened when I was not "save for the web." It seemed to me that I was trying to copy or paste or by using a different combination of keys when all of a sudden all the colors changed and I could not get back them. Cancel or cancel using the history does nothing to recover the original colors.

    It drives me crazy. I just spent an amazing amount of time - week (Yes, weeks) in fact - perfecting of colors for a site color scheme complex and out of nowhere my colors are completely foires. So I understand what happened and get back my original colors.

    I read in the forum about the possibility of having changed color settings; so I saved the file under a new name and tried other color settings, but that has not changed a thing. And if I look at the other files based on the file that has messed up (but which have original colors), color in both files settings alike. I also watched test and test colors and saw that the settings are the same as in the other case where the colors are not screwed up.

    Any help will be greatly appreciated.

    Thanks for the tips. But I has not changed anything in the color settings except in the window of the Web. That's when I left the save for web I noticed that all my colors had changed. But then again, this happened with other files and seemed to have occurred after use of key combinations such as cut and paste. I must have clicked the wrong key. But even when I closed the file without saving changes and then reopened, he still had the washed out colors. So SOMETHING changed, I just can't understand what this thing.

    ************************

    FOUND ANSWER

    It's embarrassing, but in this case, I found out something that I had moved into my open file was applied curves that touched all colors because it was near the top of the layers. I guess I didn't notice because I was zoomed in on an element. After I saved for the Web and closed the window, I noticed the color changes. In this case, it was an easy solution. But what happened before and I know it wasn't because of the curves or similar settings. Something happened which washed out/desaturated colours. I'll figure that one another day.

    But thanks to all who responded. At least I learned a few things

  • The objects will not retain any color defined when the surrounding objects have their color changed

    Just Illustrator CC 19.0.0 was downloaded to me. When I place a line and then set its color, close objects can also have their color changed. This includes the items in the file of until I added the line, not on the same map-art objects. It is not universal, nor is it compatible. Objects already in the file are perhaps there for months, but a change is close will change their.

    The Illustrator files can still be an earlier version, and there were a number of illustrations that had black lines and text to white turned a few months back. As these illustrations are for a book, being unable to guarantee that the colors will stay together long enough to complete the illustration and export it tends to make unusable Illustrator for tasks of editions. I hope that InDesign and Photoshop do not have the same questions!

    nwjh,

    You must update to 19.1 (or 19.1.1 for Windows) or 19.2 (lattethe has some problems, then you can start with the former).

    If 19.1 (or 19.2) does not appear, disconnect and then reconnect the creative cloud application. After that, the 19.1 update must be visible in the creative application of Cloud.

    My background color changes when I try to apply it. I put the color using the color picker. Then I try to create a new document with the same background color. But that change of a very different color. What I am doing wrong? I've used the previous procedure, several times, without this problem.

    The new document has a different color profile. Make sure that they are the same.

    The same result of RGB numbers in different colors in different color spaces. Or in other words, the color space defines the specific color produced by a certain set of numbers.

  • Issue with the brightness when the colors change

    I want to change the color of a building when I use the brush of color change the color looks really washed out dark red IE looking for rose. It will correct the right color if I have everything first to use the brush set of color on the brightness and then use the color value but let the texture of the building. It changes the image, the color is another way. Thank you

    You might look in a technique called frequency of separation. This would be separate your texture and color in two layers, so you can change the color without the texture. Here is an example:
