看api,Color有两个方法可以做得到 Color brighter()
Creates a new Color that is a brighter version of this Color. Color darker()
Creates a new Color that is a darker version of this Color.
Creates a new Color that is a brighter version of this Color. Color darker()

再用方法 Color.getHSBColor(float h, float s, float b)方法改变第三个参数就可以改变颜色的亮度,要怎么都可以。
