Change the color of fabric using the sun and filters?

Question

I have a royal blue backpack. I have a piece of cordura with a slightly "greener" color tone, which I'd like to use as a patch.

Is there a way to fade the fabric to make it match the color?

Like filtering the sunrays with a yellow plastic and so fading the yellow of the fabric?

Thanks,

Don't think that would work.......You may try dying the cordaroy navy blue.........
