Thousands of Bolts actually does have a color matcher and I do use it quite a lot. Unfortunately, if you already have something that is not on their site, it doesn't help. They have also added an 'on line' color chart for the Bella solids and for Stonehenge. Someone mentioned that purchasing the color cards is pricey and that is true, but the on line color charts are helpful as you can at least compare variations in shade. Just expand the number of colors per page and it helps a lot.

I did purchase a kona solids chart and find that helpful, too.
