Awesome, man. What dye did you use? 
iDye Poly.  It smells horrible, but works really well.  It even seems to work on ABS, though you do run the risk of splotching.
**** MAN! Those are so beautiful. You dyed the grey mods? If you ever want to sell those, just let me know.
I dyed the standard beige and cream set.  I don't plan on selling it, but I could make you a dyed full set easily if you wanted one.  I just have to be careful with the spacebar since I ****ed up mine while doing it.  I forgot to just use warm water for ABS.
If you want to do it on your own, I used Lilac iDye Poly.  I get it locally for $2.50 a pouch.  I used the Violet color on the white caps I had on my Qazpad:
