Horse colors

I'm making a website for my grandmother's breeding farm, and I need some ideas on what color some of her horses are.

First up is Cimarron

A Miniature x Pony of some sort Gelding.
He was about 4ish in this picture.
My thought is Wild Bay. At first I thought he may have Pangare, seeing as a ton of her previous ponies have. I can't remember whether she bred him or bought him.

Here's a few more photos.

Next up is Bro (RIP)

He was one of the riding ponies. We think American Shetland cross.
I always thought Sooty, due to his face. He also had faint dapples year round.
He was a rescue, my grandmother got him, and two others from an auction.
Here's more photos, I'm still uploading more.

Next up is Sweet Pea (RIP)

I always thought he was a Fading Black, but not positive. For those interested that's Bruce in the bg.

I have so many more.
For now I'll list their names and suspected colors, till I find the pictures.

Doc
Mini stallion. Palomino Tobiano

Barbie, Pumpkin, and the rest of that line.
Mini mares. Have no idea.

Dolly
Mini mare. Flaxen Chestnut Tobiano

Lacy
Mini mare. Black Tobiano

Robbie Joe
Mini mare. Black Tovero

Snickers
Mini colt. Flaxen Chestnut Tobiano

Lulu
Mini X mare. Dark Bay

and a bunch more.

*rubs hands together* Oh you know this is my cup of tea.

Cimarron
I would go with "agouti" because that's just obvious, and you just don't know which type of agouti it is. There are both bay and brown factors there, which make it more difficult without winter coat photos. I don't see pangare there, other than the mild muzzle and flank mealing (which could just be there if he is brown). He's not what I'd call traditionally pangare (everything below mealy, like Mack). Since it's more well-known, my final verdict on him until genetically proven otherwise would just be bay.

Bro
Since he was a rescue, and therefore I'm assuming parentage isn't known, he could have been either a light flaxen chestnut or palomino - either way definitely sooty and pangare.

Sweet Pea
Without a genetic test, impossible to say for sure whether he was black or really dark bay (or heck, even smoky black, depending on what his parents were).

Cimarron is a bay as explained by vos.

Bro definitely a flaxen chestnut with pangare, he is too reddish to be palomino and I know a flaxen that is even less reddish ( known parentage, so can't be palomino)

Sweet Pea, I need better pictures to really decide his colour and summer fur pictures. But to me he's a dark bay.
