I downloaded Cata client to upgrade from SI, so I could see my horse to be true color, However it's still Brown and should be Black.

Is there a fix i can get for this?

I have other friends that see true colors just not me.

I also can't see the the true colour of horses, sometimes i see the horses from horse routes in different colours but that doesn't happen often and it
seems that only on a few routes i can see different ones.
But the bought horses are always brown.

I also can't see horse emotes and strangely the training dolls in camelot are invisible to me, i could only get one in target when i assistet Kronos.

It's not really important but it would be interesting to know if you have the other 2 problems too.

I changed to toa client, but i already had these problems when i used cata client.

Yea like parth farm if i rent a horse its black.

I do however see dummies all around me alot.

but to stick to point the ones in TNN I can see and wack.

Take a look at the options, there should be a point - Configure Figure Versions...

There you can switch betwen classic or catacomb player/horse skins.

In classic-mode are all horse get the same color.
