Change the color of a child

Hi! Here's my problem, I have a rigidbody, it contains a determined number of childrens (without rigidbody). I want when the player passes de mouse over, the child change its color. But OnMouseOver don't work if I have a rigidbody attached to the parent.

Any solution? Thanks!!

Attach the script to the parent not the child. you would also have to get it to only affect that specific object.
