Hello marisol! These terracotta powders are ideal if you want a more natural effect. The difference between 02 and 03, is only that the tone rises a bit, both in the darkest color, in the middle and in the pink that includes makeup. To help you better, shades 00 and 01 would be for fair skin, shades 02 and 03 for medium skin and 03 and 04 for very tanned skin. All the best.
