I want to spin a peacock

If you have ever met, and heard, real live peacocks, you know you do not want me to actually spin an actual peacock. However, I want to spin something like one. What do you think of these colors?









(And yes, I finished the last of the rose quartz last night - it's setting in the bathroom right now, yucky smell, lovely yarn!) Imagine these spun up in sections, randomly, then plied together. Or maybe divide the colors into families and ply the purple blues against the green blues?
Does it need a true green as well?
