...Most of the colors share some of the same words such as "light" blue, "light" green, etc.
Here is what I think is a problem. When I go to Google Webmaster Tools Keywords page it will list words like "light" as the most common keyword instead of the actual product.
If only a few repetitions of "light" are enough to skew the content profile of your pages for Google, your content is weak in any event.
This suggests that adding more unique content about the product is going to be your most productive approach overall.
Putting the colors in an iframe might mask the symptom, but it wouldn't strengthen your content, which it appears is what you need to do.
