I have exactly zero idea how feasible this would be to code as it would involve introducing a whole other element into how colors work, and I also don’t really know how many other people would actively want this because it would make breeding projects less challenging and therefor good color combos less rare but:

Perhaps having values (i.e. light and dark) assigned to each color and assigning a certain chance of an offspring inheriting a gene’s value and tone.

For example, if both parents have “light” unders, their offsprings having a 75% chance of also having light unders and If one parent has a “dark” under and the other parent has a light under it could be 50/50.

I find the value of the colors to be maybe even more important than the tone and looking at potential offspring, other’s pups, and wolves listed in the flea market, I find myself thinking that it’s such a shame more of them didn’t have values more similar to their parents.

For sake of simplifying this I would guess it would be only light and dark and no middle values. I’m assuming adding even just what I’ve suggested would be quite an undertaking!

Again, I really have no idea if anyone else would want this or how feasible this would be, just a thought, please don’t hurt me.

Against. I think keeping the color wheel simple to understand and use is important, and this would add unnecessary complexity.

Definitely against, I'm sorry. I've been part of sites that do stuff like that and it just makes the breeding mechanics more confusing and frustrating. The breeding system as it is is easy to understand, which is how things like that should be on pet sites.
