My Donna Dewberry mat is light blue on one side and light lilac on the other. I don't know if that is light enough to help.
I originally bought it because it was the biggest I could find for the money. I've had it for 2 - 3 years now and have no complaints.
Here is a link to a page with a picture of it. I didn't buy mine from here. This was just the first picture that came up in Google.
