Colour matching Turtles

I borrowed a Pantone wheel from a friend to match the colours on the TMNT playfield for the overlays I'm making. It wasn't that easy, however. It seemed the Pantone wheel didn't have all the colours I need, or did the playfield fade? I definitely couldn't find a perfect match for every colour, but it's better than nothing. The alternative would be me test printing colour samples, a very tedious job.

What surprised me was that the wheel didn't include CMYK or RGB values, just Pantone colour names. I Googled a bit and found some RGB values. Here's what I have so far.

The top (left) overlay:

Red: Pantone 199C (216,28,63)

Blue: Pantone Process Cyan C (0,159,218)

The bottom (right) overlay:

Yellow: Pantone 109C (249,214,22)

Solid red/orange: Pantone Warm Red (255,64,25)

I am starting to doubt the final results a bit, as I am going from "almost correct" Pantone colours through RGB conversion to CMYK. We'll see how it look when it's all done and printed.
