No I’m on Mac. That looks really cool, I’ll try it out. I’ve got the Adobe phone app that lets you turn photos into colour palettes, which is useful sometimes.
I try my best to avoid work with strict style sheets these days. I used to work doing catalogues 
(Even worse I worked at an art supply merchants and used to make colour charts of photographed paint, pastel etc samples. Hundreds of pages of the things. I’d see coloured squares floating in front of my eyes constantly)
