Dang, given all the cool visual work on your website I absolutely would not have expected that. Always good to be reminded how disparate we all are from one another.
Makes me grateful I got my mom to sign that waiver to let me get on Neopets, I don't even see the hex code anymore, I just see marigold, umber, vermilion.
Take care here though, because shaders are almost always working in linear sRGB colors, while color codes are almost always defined in gamma-encoded sRGB.
This property makes it mildly annoying to copy color constants between different contexts.
