I use KDE Plasma, and much prefer the KDE color picker over the GTK one that Firefox uses, with input type=color.
I know that I can set GTK_USE_PORTAL=1 to make Firefox use the native file picker, is there a way to make it use the native color picker as well?
I know there probably isn't a way, but I figured it's worth a shot asking.
unless you tell them which company's color codes you used to match the names to rgb values this will be more useless to artists than rgb colors without a color preview. Text based colors are purely subjective and you'll be hard pressed to find two companies using the same name for the exact same color mix (you will find companies selling paint under the same name but it sure as hell won't look the same). The closest you'll get are the css default colors but that's a pretty limited selection of colors so with your genius text input method you'd still need a couple of sliders to get the entire color spectrum.
Your idea has merit but not for artists. Casual people would benefit a lot more from it, because they won't have to struggle finding the correct color for what they want most of the time. But even just hobby digital artists will spend more time wrangling with your text input than they would just hand picking the rgb values, never mind professional digital artists who probably don't even think in named colors anymore and just think of the rgb ranges they want instead.
