Add a border

HI,
Very good plug in.
My issue is, when i’m add a white color attribute to a product, on the Product page the product color is merging with the background :((
Maybe there is a way to add a border around the colors, that way a border will allocate the white color and the other color also.

Below is a link to see the issue:

Thank for advance.
