Frost is a material type introduced in Kingdom Hearts. Frost materials contain the essence of ice, and are colored aqua.

Design

Frost materials are represented by aqua blue jewels with what seem to be small, white, ice crystals covering them. They have an Elemental material structure. In Kingdom Hearts 358/2 Days, they are purple.

A "frost" is a cover of minute ice crystals on an object, reflecting the apparent frost covering the material, as well as the "essence of ice" the material contains.
