# Programmatically set color of Box2D body's sprite or image

In my basic Cocos2D + Box2D iPhone app I have a bunch of circular Box2D bodies. I'd like to change the color of the circles programatically. What's the easiest way to do this?

So far I'm just assigning a CCSprite* to the b2body->userData. So perhaps I can change the colors in my sprite sheet programmatically? Seems like there's an easier way. I'm just not sure what it is.

Cheers!

cocos2d CCSprites have a three byte color property. You can use it like sprite.color = ccc3(r, g, b).
