What to add to Cherries?

[HybridHerp]

So, I have a tank with some red cherry shrimp in it and was thinking about adding another variety of N. heteropoda to spice up the population. I'm not really sure what direction to take it in though.

Here are some of my ideas:
1. get some higher red varieties like painted or fire to increase the overall intensity of the red color I am getting in my cherry shrimp
2. Rili so that I can overtime have that new expression coming out within my population
3. Yellow/Blue/Chocolate/ect. so that I can make some sort of mixed color of sorts or have a ton of variation within clutches (or will these mixes only result in a ton of wild type looking clear offspring?)

yah, so I have ideas but not sure if any of them are good ideas lol
