Has anyone else noticed how many balls have been released lately with this color combo?

1. 2 Furious
2. Reign Supreme
3. Damage
4. Theory
5. Shredder
6. C-System 2.5
7. Complete Bedlam ( has a touch of purple)
8. Blue Death
9. Ultimate Power
10.Aftermath (pearl version)
11.Tropical HEAT (One of the three)

 And this is just some recent balls I can think of. Seem like a bit too much?
