Material.SetColor

Switch to Manual
public void SetColor(string name, Color value);
public void SetColor(int nameID, Color value);

Parameters

nameID Property name ID, use Shader.PropertyToID to get it.
name Property name, e.g. "_Color".
value Color value to set.

Description

Sets a named color value.

Many shaders use more than one color. Use SetColor to change the color (identified by shader property name, or unique property name ID).

When setting color values on materials using the Standard Shader, you should be aware that you may need to use EnableKeyword to enable features of the shader that were not previously in use. For more detail, read Accessing Materials via Script.

Common color names used by Unity's builtin shaders:
"_Color" is the main color of a material. This can also be accessed via color property.
"_EmissionColor" is the emissive color of a material.
