The style.css file for the Classic theme contains codes for colours that are only three digits long. Normally (?) HEX refs are 6 digits long. If I insert the 3 digit codes in the file into a converter eg: http://www.scriptsearch.com/cgi-bin/jump.cgi?ID=1178
they are not recognised.
Can anyone explain what these 3 digit codes are and how to translate them into the "normal" 6 digit ones (or into RGB)?
