I'm trying to adjust the colors of the NetLogo interface for images which will go into a book. The light purple or aqua colors of the controls and the beige-ish border of the plot are not ideal, as they will be grey in black and white and make the text harder to read. I've checked the NetLogo documentation for some way to edit these, and I can't find anything about this.
Is there any way to change the color on these?

I do a lot of Zoom quizzes, and am always looking for new and interesting rounds to include. Recently I saw a screenshot of a quiz where someone had taken album covers and rearranged the colours in the image so that all the darkest colours were in the top left and there was a smooth gradient to the lightest colours in the bottom right.
I am basically looking for a way to do this myself. Is there a tool on Gimp that will allow me to rearrange all the pixels by their colour value in a smooth gradient? I'm not tied to Gimp and would be open to trying other programs that could do this.
Thanks.
I wish to have a transparent terminal.
In order the view the letters without increasing the font size, I would like to have a contrast by coloring the text's background.
Does anyone know of a way to do this? Perhaps installing a special font?
Your best bet would be to use bright colored text. I was just experimenting and it seems like a good, bright red stands out on most backgrounds. You can also experiment with the blur effect your terminal has. A higher blur will allow for more background contrast. I did not see a way to color the text's background color itself though.
How to programmatically change the hue of UIImage?
I am using the above page's advice, for Core image filter CIFilter. The only problem I am having is my when I rotate to a yellow hue, it's a dark mustard yellow, and I can't get the brightest vibrant yellow, ie R:255 G:255 B:0. I have images that are on layers that are made up of a simple color R:255 G:0 B:0 I just want to rotate around, to get the basic colors plus orange. Orange works fine tho.
I just don't know why when I rotate from R:255 to try and get R:255 G:255 Yellow it's a dark yellow.
I am using 1.04719755 for the Yellow float, at deltaHueRadians
I don't know it's just weird this is the 3rd attempt at this but I keep getting a dingy yellow.
I realized the problem.
In Photoshop I have done so many Colorize operations when I used to photo edit, I got them confused with Hue Rotation.
Basically when you Colorize in Photoshop, it will "Colorize" the image not just Hue Rotate the values.
The difference between the two is a very thin line depending on what images you use. I don't really feel like going into a complete explanation but...
Say you have a grey cube on a layer, and you COLORIZE the image, the cube will rotate colors as you use a slider. If you Hue rotate it will stay grey.
But if you take a red cube, and hue rotate, then the hue rotation will take you thru colors, not necessarily all of them tho like a colorize.
I believe the issue has to do with all that good ole HSV RGB matrix crazy math problems. Which I am not doing right now. Keeping it simple.
I decided to just do a colorize method with:
CGContextSetBlendMode(context, kCGBlendModeMultiply);
With grey objects and this is perfectly what I wanted.
from googling I found this:

Here is a color wheel, typically from the web. I would like to create something like the user input the Yellow color code, and I am able to find the complementary color of Yellow is purple. Also, I would like to find the nearby color, light green, and the light orange. How can I implement it in a computer science way? or any existing algorithm to do so? Thanks.
I have a table in which the cells may contain normal and grayed-out text. The color for normal text is chosen dynamically according to this post in order to take account that the table's background color is theme-dependent. Now I'm wondering if there's any good way to determine an appropriate "gray" color based on the table's background, so that:
the "gray" is "really" gray when the background color is white or black
the grayed-out text is readable with all possible background colors
if possible, the grayed-out text should be distinguishable from normal text, and ideally look "paler", in the same way that gray is paler than black
Note: Other styles, such as strike-out, are not appropriate in my case, since the gray color is used to convey the idea of a table cell being "less important" than others, rather than being obsolete/unavailable/etc.
Well, your linked question selects only one of two text colors: it will be either black or white.
Did you try to just use a "dark gray" when the text color is black, and a light gray when the text color is white?
