Hi,
Thanks for all your comments.
I'll look at the CSS spec. I'll look at the 4 bit RGB,
i never heard of this before.
Since CSS and the 4 to 8 bit conversion tells me to
use #ff2233 from #f23, i'll make the change and "i'll
get to bed less stupid tonight" (french expression).
Thanks everyone for your time,
Robert

more likely f23 = f2 30 00 or 00 0f 23 :)
It makes perfect sense. "#f23" specifies an
RGB-triplet with 4 bits per
channel and "#ff2233" specifies it with 8 bits per
channel.
When converting from 4 bits per channel to 8 bits
per channel one
multiplies each channel value not by 16 but by 17 in
order to cover the
whole range properly (so F maps to FF instead of to
F0).
