Replicating Badlands terracotta stripes more efficiently?

Hi all, I'm making a custom biome that's more or less a badlands variant. 
I wanted to know if there's an easier way to do custom stripe colors other than placing down a ton of predicates for y-level-related rules (such as y_above maybe with absolute values, etc). I'm wanting to not use the pre-existing stripes pattern that the default badlands uses. 
If there is a better way, then what would be the best way to go about it?
