A tutorial on how to make a unified color palette, aka how to make colors look good next to each other. Not a lot of people understand how color works, and while this isn't the end-all be-all, it certainly helps when you're stuck.
A life changer for me, this. Had a super hard time picking nice colours due to my wonky colour vision (red/green. Not severe, but bad enough) and these tricks just made ALL the difference. Thank you so much. Can't believe I haven't thought of this sooner. It basically simulates the colour of the ambient lighting adding to everything.
