Minecraft wiki entry for Pixel_art, associated text: Creepers are ugly in their colors, so use plenty of different colors when making a creeper with pixel art. Use lime wool/concrete, green wool/concrete, white wool/concrete, and light gray wool/concrete for different parts of the creeper. If you want even more variations for colors similar to these, use the same colors but in terracotta for some parts of the creeper, so that you can have a slight contrast. Also, you may want to use blocks that are not wool, concrete, or terracotta, such as stone or slime blocks. The most important thing when making a creeper is to line the blocks up perfectly with the pixels on the creeper's face, as this is the most noticeable part.
