Electric Blue is a color that can be selected in the Roblox Studio color wheel, and has a "number" of 315 (source). It can be used to color parts and meshes alike, although it can only color a mesh if it has no texture already. Otherwise, the texture covers the colored mesh.

it also looks really rad (hence why it's called electric blue) :]
