Unity makes image colors glow

Color color = GetComponent<SpriteRenderer>().material.color;//记录原颜色
Sequence quence_material = DOTween.Sequence();
quence_material.Append(GetComponent<SpriteRenderer>().material.DOColor(color * 1.1f, 0.1f));//让颜色乘一个系数
quence_material.Append(GetComponent<SpriteRenderer>().material.DOColor(color, 0.1f));//恢复颜色

You can see that the changed color square is obviously brighter than the original square color
