Interested in what field you get the term ‘rgb float’? Not a term I’ve heard before (and not an accurate one) so I’d be interested if it’s a term of art in some industry...
Computer graphics use floats for color values very often. It was indeed misleading of me to mention floats and then use a hex value to explain it, though. Just a brain fart from seeing it earlier in the thread. With floats it would simply be (1,0,1).
