Oh, ok. Print them from an Inkjet color printer on to an Inkjet overhead-projector transparency, something like this.

I actually print them twice on the same page, to get better color saturation and prevent little white lines from being a bother.

Almost any inkjet printer will do nicely, but depending on how accurate your color rendering is, and what kind of color inks you're using, you may have to tweak the color slightly to get a perfect match. Make sure to use Inkjet transparencies as other kinds won't work in inkjet printers (the ink won't dry).

Then just cut it out and place it behind the amber screen, and put the player back together.

Voilà!
