Linux commonly expresses colors as hexadecimal rgb color codes and color names. Hexadecimal color codes are 6 characters often prefixed by a pound sign (Ex. # 000000). Each pair of characters ranges from 00 to FF (equivalent of 0 to 255). The first two characters represent red, the middle two characters represent green, and the last two characters represent blue. # FF0000 = red # 00FF00 = green # 0000FF = blue # FFFF00 = yellow # FF00FF = magenta # 00FFFF = cyan # 000000 = black # FFFFFF = white Color names are an alternative to hex color codes.

Chrome Unboxed has an article that covers enabling high contrast: chromeunboxed.com/invert-your-chromebooks-colors-high-contrast-mode-and-other-accessibility-features/
Thank you @ruthake for a very informative video. I just have one piece of constructive feedback ... the plural for "screen-full" is "screens-full" ... a bit like "cups of tea" instead of "cup of teas" ... anyway, hope this helps. Keep up the great work & go Linux =)
