ColorUtility

With the aid of ColorUtility you can use a color picker to find out the RGB, HSV, ASCII and decimal codes of any color from your desktop. This is an intuitive software application that features just a couple of customization preferences.

No setup necessary, besides .NET Framework

Provided that you have .NET Framework installed on your PC, you don't need to set up anything else. This way, you can save ColorUtility anywhere on the disk or on a removable storage unit, and just click it to immediately launch the app on any PC with minimum effort. Plus, it doesn't change the Windows registry configuration.

Clear-cut interface and options

The user-friendly GUI is made from a small window split into several panes dedicated to RGB, HSV, filters, settings, and other tools. It also contain a tiny frame for previewing the selected color.
Discover the codes of any desktop color

You can click and hold a button to use the color picker, as well as release it after finding the target color. The tool immediately reveals the ASCII, RGB, HSV and decimal codes, giving you the possibility to copy them to the Clipboard.

Manipulate colors and copy their codes

It's possible to tweak the RGB and HSV levels, negate the RGB values of the color, convert it to greyscale or sepia, intensify, brighten or darken the color, display only the red, green or blue channel, as well as shuffle the red, green and blue channels.
Other utilities supported by ColorUtility let you combine two or more colors, obtain all colors from any image file you load, as well as create a random color by applying simple or advanced settings.

Evaluation and conclusion

As expected, the software program didn't put a strain on the overall performance of the machine, as it needed low CPU and RAM to work properly. It didn't hang, crash or prompt error dialogs.
To wrap it up, ColorUtility comes bundled with a surprisingly rich and practical set of options for discovering color codes, and it can be handled with ease by anyone.
