Im having a bit of a struggle understanding the wicked color names. They have transparant white, but no transparant black? They have standard and detail. Now when you reduce them witch one gives me transparant black? I do now from an earlier post i saw on this forum that there is more fine pigment in the detail colors and that the w500 reducer is better then the w100 (tipdry). But i can only get the w100 around here. And do you have to use the reducer from wicked or can i use anything else to reduce the paint?
