# Color

You can specify a color property to apply to a custom machine model.

This property must be specified inside the `appearance` property.

The color must be an integer of type: 0xRRGGBB: go [here](https://www.shodor.org/stella2java/rgbint.html) if you don't know how to calculate an integer color from RGB values.

The color will only be applied to faces of the model that have `"tintIndex": 4` specified, all other faces will be ignored and not be colored.
