Sets a 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.
Color property names are defined in the Properties section in the shader code. Here are examples of the color properties in Unity pre-built shaders:
_Color: the main color of a material (URP: _BaseColor). You can access this shader property via the color property.
_EmissionColor: the emissive color of a material.

//Attach this script to any GameObject in your scene to spawn a cube and change the material color using UnityEngine;
public class Example : MonoBehaviour { void Start() { // Create a new cube primitive to set the color on GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
// Get the Renderer component from the new cube var cubeRenderer = cube.GetComponent<Renderer>();
// Use SetColor to set the main color shader property cubeRenderer.material.SetColor("_Color", Color.red); // If your project uses URP, uncomment the following line and use it instead of the previous line // cubeRenderer.material.SetColor("_BaseColor", Color.red); } }
