Color Sampler 1.0

Press alt and point (you don't need to click) at any color anywhere on your screen to see its RGB and hex color value instantly. Click the Color Sampler window to copy the hex code to your clipboard.


Love the color of something in a photo, a web page, a video, the background of some app's window, even an app icon in the Dock? Use Color Sampler to find out its RGB and hexadecimal color values.

Color Sampler floats over all your applications. When its window is active, hold down the alt key and point at anything on your screen to sample its color value. Release the alt key to freeze the sampled color values, and click on the Color Sampler window to copy the hexadecimal code to the clipboard.

Color Sampler is free, but if you like it feel free to throw a bit in the tip jar (PayPal link below). Thanks!

(Or if you have a PayPal account this link is quicker.)

If you prefer bitcoin you can throw in a tiny fraction of a BTC bitcoin: BTC code 1AT2TcPjBHMZdLEWtXs2zE6tvGbyDNJxW7.

Tips are used to help offset the cost of my software prototyping and development tools and are greatly appreciated.


First-time launch: Mac users may need to open this app the first time by right-clicking/control-clicking and selecting 'Open'. Windows users may see a one-time warning about allowing unauthorised applications to run. In both cases this only happens once.

Virus warning from Avast anti-virus software? In 2016 and again in 2017 a version of Avast's security software for Windows reported the Win32:Xpaj-gen virus inside the zip archive. This is a known 'false positive' alert, and it has been fixed in the latest Avast updates. To be 100% clear: the virus report by Avast software is a false positive; the zip archive is clean, and updating the Avast virus definitions cures the problem.

This software is free to use, of course, although tips help me pay for my development costs. Bug reports and questions are welcome – you can find me on Twitter (@thatkeith) and Facebook (
