colour_board - written in python, displays the colour for the pixel in the middle of your screenshot, designed to be used with Windows Snipping Tool (win + shift + s) but it should work on all platforms.
colour_board_debug is an alternative version that will save the image in clipboard to a "temp folder" used to debug.
