3DS Max Vray Sun Shadow Colors


Hey All…
Long time Googler, first time poster.

I have a question about colored shadows cast by the Vray Sun.
I’m trying to have the shadows of the fabric to retain thier individual colors.
The Vray Sun casts shadows as shades of gray.

Is there something that i’m missing?
Will i have to swap my Vray Sun light for something else?

Here’s an example of my render:
