For axiom (red, green, blue), the base color doesn’t matter when they are homozygous. It matters what two colors of axiom you combine.
So axiom red/green turns yellow

AHH Fundamental Pockets

Axiom green/blue turns aqua

G1 Neptunes Kuiper

Axiom red/blue turns pink/purple

Neptunes Folly

Onyx only requires one copy to show. I don’t really think nd1 affects it at all, and onyx/dun creates a ghost type effect.

This is Dun/onyx

Just like FallenShadows said, I am not sure about nd2 making any difference with onyx. I find the darker the coat the better the onyx can be seen although I have seen some gorgeous ones in more subtle shades.

I don't know much about the closed gene axioms but I do have a lot of nexus.
Since nexus inverts colours horses with varying shades to them seem to express better. The darker the horse the lighter the nexus will turn out. Black horses with nexus are just grey.
Liver gives some neat bright blues but if you want those cool oil on water kind of expressions horses that carry pearl, cream, and champagne are the way to go.
@Cheers has been working on some very informative threads on colour expression and has an excellent one covering the different potential nexus expressions on different coat colours. I am on my phone and can't find it.

Chinchilla is my jam! My favourite expression is on silver blacks but brown and bay chins can be nice too. With the brown and bays, if you want to see decent expression you want some darkening genes on your horse like sty, S+, and/or DP. Chinchilla needs black or E to be able to show. A chestnut horse is just going to turn out all white.

I love mixing and matching fantasy genes on horses to see what comes out, wrong warp is a particular favorite

Axiom tends to over-ride whatever colour it's put on to a large extent, so base colour doesn't matter that much. Nexus however yes you can see ice genes, watercolour etc through it so can get some great affects!

I second chinchilla being an awesome gene, most of my horses are silvers so it fits in well in my herd, and looks fantastic with other ice genes, watercolour etc too!

This is the Nexus thread: https://hj2.huntandjump.com/forum/discussion/65079/nexus-variations-due-to-normal-base-color#Item_67

The first page or so is the most informative. Basically the darker the coat would be on a normal horse, the lighter it is with hom Nexus and vice versa.
