Basically, a "Refractor Rainbow" is our way of showing you how a Topps product's refractor system works. Parallels are among the most confusing thing in cards and hopefully this helps, I'll do my best to provide a "Refractor Rainbow" for upcoming products to help alleviate future confusion.
Below is our 2010 Bowman Sterling Baseball refractor raindbow, which is relatively simple seeing as how their are only 5 different possible refractors. As noted below, the purple refractor /10, also known as the "reverse negative refractor" due to the backwards card text, is the only refractor that doesn't translate to autographs. Printing plates are not included, but I tend to look at a printing plate as a 1/4 rather than a 1/1 due to the fact that each product seeds a total of 4 of them (yellow, black, magenta and cyan).
