Body Color

Is there a way to create an expression that is linked to body color without Knowledge Fusion? I have expressions that check for size. When certain sizes, I want the body colors to be corresponding colors. I want it to update the body color when the size changes. I was hoping there would be a journal that could create this expression link to the part attribute for me.

Thanks,

Wayne

I don't know of any way to link an expression to a body color.
