+### MaterialColors
+
+For both implicit and explicit values, the type is an object that looks like this:
+
+```json
+{
+	"$properties": {
+		"ImplicitExample": {
+			"Grass": [10, 20, 30],
+			"Asphalt": [40, 50, 60],
+			"LeafyGrass": [255, 155, 55]
+		},
+		"ExplicitExample": {
+			"MaterialColors": {
+				"Grass": [10, 20, 30],
+				"Asphalt": [40, 50, 60],
+				"LeafyGrass": [255, 155, 55]
+			}
+		}
+	}
+}
+```
+
+The key-value pairs within the object should be [Material](https://create.roblox.com/docs/reference/engine/enums/Material) enum items mapped to arrays of 3 integers representing the RGB of the specified color. Only the values you wish to change the defaults of need to be specified.
+
 ### NumberRange
 The NumberRange type cannot be specified implicitly. For explicit values, the format is a list of Min and Max components, respectively. Each component is a float.
