# color

The color value for the material property.

## Declaration

```swift
var color: CGColor? { get set }
```

## Discussion

Discussion A material property with a color value uses a uniform color for all pixels rendered using the material. This option is useful for base colors of solid-color objects, and also for material semantics where variation across the surface of the material is unnecessary. To vary colors across a surface, use a texture image instead.
