| name | The name of the property. |
| nameID | The name ID of the property retrieved by Shader.PropertyToID. |
| value | The Color value to set. |
Set a color property.
Adds a property to the block. If a color property with the given name already exists, the old value is replaced.

Function variant that takes nameID is faster. If you are changing properties with the same name repeatedly,
use Shader.PropertyToID to get unique identifier for the name, and pass the identifier to SetColor.
