Arcane Scholar

Arcane Scholar is an epic skin from the Heroes collection. It's a masculine look, drawn for the classic (Steve) model with 4-pixel arms, so choose that arm type when you apply it.

The palette is a grey hood, a dark indigo starfield top and dark indigo legs. Look for glasses and a beard. Download the 64×64 PNG, then upload it under Skins in the Minecraft Launcher for Java Edition, or import it from the Dressing Room in Bedrock Edition.
