I ws wondering if anyone was using a dynamic color for easy understandig of a grids data?

I have a signature loan customer who will take 5 to 10 payments on a loan. I want to show in a grid for payments where the customer stands.

Issues that come to mind are past late payments in a blue color, current payment in red and special extensions in green.

Where would I put in the flaging for various colors? Should I add a column in the view that I record the color? That way every time in the future it's already done?

Next is how would I change the color? I the page.activate pem ?

TIA
