As far as I know the John Deere line offers a wide range of colors. Let's see there's gloss yellow, green, black, and Blitz Black!
I think black is the only color in they're lineup with the name Blitz in it, and the only flat/satin colored paint they offer.
Their paint is produced by Valspar, and I would imagine Valspar offers a lot more colors in their product line. From my experience however the JD Blitz Black must be a unique formulation as it doesn't seem to be identical to anything in the Valspar line.
