For a rubber ball, you could use a black or red specular light instead of white which would make the ball appear less shiny.

而对于橡皮球，你可以使用黑色或者红色反射光代替白色以使得球看上去不那么闪。

It is a red rubber band left there by the postman. When my elder son was little he would seize on these bands and add them to the giant rubber band ball he was making.

在我的大儿子小的时候，他会利用这些橡皮筋，把它们缠绕在自己制作的巨大橡皮筋球上。
