colorsscreen capture
I have a screen capture of some colors I'd like to use. I need to learn their hex codes. I have the screen shot in MS paint. I can see where I can pull the color with the dropper, and where I can define custom colors, but I don't see any place where it tells me the hex code of the color.
Can I do this in mspaint, or gimp?
In Windows, there is an easier way that doesn't need any software.
Looks like this should do what you need.
Simply pick up the app's icon from your system tray, drag it toward the color you want to find, and a magnified, pixel-by-pixel view lets you pinpoint exactly what shade you're looking for. The color code—HTML, RGB, or whatever you prefer to set in the options—is instantly copied to your clipboard for easy pasting in any editing tool.

After you select color with Dropper, go to Tools->Edit colors and click on Define Custom Colors. On right side you will get three numbers (Red, Green and Blue). Convert those numbers to their hexadecimal form (Windows Calculator will do) and just have them one after another (Red, Green and then blue).
This is as far as I know only way to do it in MS Paint. However, You might think of Paint.NET or better editor as alternate solution since almost all other image editors do have that feature available.
