| hasAlpha Accessor ReadOnly | boolean | Whether the color(s) in this index have transparency. | |
| isUniform Accessor ReadOnly | boolean | Whether this index specifies a single uniform color for the entire mesh or polyline. | |
| nonUniform Accessor ReadOnly | undefined | NonUniformColor | Returns the per-vertex colors, if isUniform is false; or undefined otherwise. |
