how to achieve complex ocean variation in color

[miguelortega]

I have seen a few tutorials where a bifrost color set (velocity) is turned into a mask to blend a foam to a water shader.
>Bifrost
>color set to vertex color
>vertex color to remap hsv
>remap hsv to blend amount of blend material (of foam)

when i do this i dont get the results i want, and also the rendering slows down dramatically.
what is the best approach to get more complexity in my water shader?
I want to see more than just foam but variation in color.

any tips appreciated.
