Ember Tide

Ember Tide is an epic skin from the Duality collection. It's a feminine look, drawn for the slim (Alex) model with 3-pixel arms, so choose that arm type when you apply it.

The palette is red and cyan hair, an orange scaled top and cyan legs. Look for long hair. 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.
