I hate srgb, but using html code is worst for povray. Within html, you
are limited to 0-1 range... whereas <..> notation is not. I like
"negative colours". And hdri like big ones!
If you want pre-gamma correct value, maybe its time for a
"srgb"/srgbf/... additional color code, specifying color in the silly
sRGB space (and then parser will gamma correct it to linear space on the
fly) BTW, would you gamma-correct F or T ??? why ?
Beware, valid html code could be #fff, #ffffff or even bigger (never
seen, but possible, any multiple of 3 symbols is ok; worse, a multiple
of 4 symbol might be rgba space... guess what happened for a 16
bit-component rgba vs 12 bit rgba : you cannot be right) but who cares
with today 5/6 bits LCD screens!
If you want #7FBFFF ... might I suggest a macro for that ? or just go
for it, but srgb seems cleaner to me.
