I should've mentioned that race isn't the bulk of the story.
The story is about two sisters who are the victims of a horrible crime. The crime is only hinted at but readers will know it's bad. The sisters are taken in by a kindly old woman who lives in a nice village. The older sister runs off, everyone assumes she's dead. A couple years later the older sister reappears. Only now she's batshit crazy and she kills a lot of people. She kills some people the younger sister loves and the younger sister has that "I'm going to kill that crazy bitch" moment. Etc, etc.
So the who racism thing is in the background. The sisters are red furs and so are sort of in the middle of fur hierarchy. The little sister's love interest is a gray, so he's the one who suffers prejudice and it makes their love forbidden which is the best kind of love.
Typical fantasy stuff.
The story is less on the nose about racism than the "Planet of the Apes" movies. It's more about defeating a greater evil with a "don't let others define who you are" theme.
But there are inns who won't serve the love interest because he's a gray.

I guess the problem you are going to run into is that your whole fictional society seems to be based on race. In particular, colour. Therefore, you're right to want to be careful. Whether you want to or not, the story is going to reflect racism very much on-the-nose from the sounds of what you're describing.
It's interesting because very few animals base their hierarchy on colour. Most primates, for example, form theirs around gender, size, and health.
Humans, on the other hand, find any reason to differentiate groupings/tribes that suits their power/political/economic purposes. In my birth country of Former Yugoslavia, people literally went to war because one sect believed priests could marry and Christmas was 2 weeks later, and the other didn't. Well, that was what the guys with the guns were sold. The actual war was about power and stealing wealth, and that was driven by the silverbacks at the top.
My feeling is that Marx had it right. All conflict comes down to wealth and power - "the Class Struggle". My long-winded point is that if you want to stay clear of skin colour, pick any other feature, and it will serve your purpose. As long as there is an unequal distribution of power, your Simians (who seem very human-like) can find a way to differentiate themselves with propaganda and dogma in order to keep the status quo.
Take my opinion with a huge grain of salt.
