Im making wedding cupcakes/cake and the brides colors are champagne pink and beige anyone have any idea's how to achieve a good color for either of these?

a touch of pink...very light...

like wilton rose?

Try Wilton light pink rather then rose. Rose is a much more deep pink. Start with a very small amount of the light pink and if you feel it needs to be a deeper pink then you can add a tiny bit of the rose. Remember less is more!
