This is a demo requested by @hinkonar. Click where you want to place the crosshair, and then click the green flag and enter the hexadecimal code for the color you want to check the distance to. The crosshair disappears while it searches for the color. Just wait a while and it will be back.
Here are the hexadecimal codes for the colored circles: #cdcdcd - gray #ff6666 - red #666eff - blue #ff66e8 - magenta #9966ff - purple #66fbff - cyan #6cff66 - green #be5f4c - brown #fff666 - yellow #000000 - black #ffb2b2 - pink #ffac66 - orange #ffffff - white Note that the color names above are only loosely descriptive - they aren't the name for the specific nuance. Also, not that the block "touching color ..." can report true not only for the specific color you've entered, but similar colors as well.
