| Parameter | Description |
|---|---|
| a | The start color, returned when t = 0. |
| b | The end color, returned when t = 1. |
| t | The interpolation ratio. The ratio will not be clamped, and can be outside of the [0; 1] range. |
Color
The color resulting from linear interpolation between a and b.
Linearly interpolates between colors a and b using the interpolation ratio t.
t is clamped to be between 0 and 1. When t is 0, the function returns a. When t is 1, the function returns b.
If t is less than 0, or greater than 1, the result will be linearly extrapolated from a and b. For example, Color.LerpUnclamped(new Color(0.0f, 0.0f, 0.0f), new Color(0.5f, 0.5f, 0.5f), 3.0f) will return a color given by new Color(1.5f, 1.5f, 1.5f).
The script below will set the color of MeshRenderer to the result of unclamped interpolation using parameters specified in the inspector. To use the script, attach it to a GameObject with a MeshRenderer.
using UnityEngine;
[RequireComponent(typeof(MeshRenderer))] public class ColorLerp : MonoBehaviour { public Color colorA = Color.white; public Color colorB = Color.red; public float interpolationRatio = 0.5f;
private Material material;
private void Start() { material = GetComponent<Renderer>().material; }
void Update() { material.color = Color.LerpUnclamped(colorA, colorB, interpolationRatio); } }
