"#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). -Peter
