I was given the basic set without the dice, so my first dice set was from the expert set...I never coloured them in with the crayon cause I thought that was stupid and I've always been able to read them fine.  I have all save the d4 and d10.  They were multi coloured, d4 purple, d6 dark blue, d8 light green, d10, light blue, and d20 light blue.  I don't know if this was standard or not...it always seemed a bit odd for colours...and I've heard conlicting reports from other people.  But, there were different printings.  I still keep them with my Chalice-o-Dice.
