hmm to me is not really logical to make f23 = ff2233 at the most 0f0203 but even that is stretching 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).
