Anyone know the colour of my boy

Unusual colour, unknown breed.

This is my eventer, his name is Raffles
I was told he was a TB when I bought him. But I don't believe he can be a TB with his colours as there are no dilutes in the TB gene.
His colour: bright chestnut, black points, white socks, black/flaxen mane and tail, blaze and white splodge on cheek.
His brand is script W over inverted wings, 3 over 6 (Australian brand)
His mane is not sun bleached as he is covered 24/7 .

Any ideas on breed or colour?!??! Would love to know!
I have been telling people he is some sort of paint

He's so cool! Silver bay? I agree he's not a pure TB, but looks like he has a lot of TB in him, I love his white cheek!

He looks a lot like the AQHA I ride... His forelock is so cool. Gorgeous boy!!

My first thought would be to check out if he is TB or not. Give the Australian Stud Book a call, and they should be able to check if the brand is a TB one. If it is, they will even be able to tell you what his registered name is.

I am inclined to think he is wild bay if he is TB. If he isn't a TB, then I have a few other guesses, but don't want to go out on a limb yet.

For what it's worth, we do have cream dilution in Australian TBs now. It's come from the US, and there are a few studs that stand diluted stallions. However, I don't think it's very common yet, and it's probably not the cause if he is a TB.

Please post some untacked side (conformation type) pictures.

Thank you everyone. Yes I was thinking silver bay however he seems way too red for that as all the photos on google are very dark and have white/golden mains, unlike Raffles who seems to have black in there as well. I have been on the ASB website and I don't think they have a record of his brand but giving them a call is always a good idea!

Photos of him with no saddle:

He definitely looks like a TB to me, with those shark fin withers lmao.

If it helps he's 15.3hh, 12yr old
He has flecks of white through his rear end
Has the movement of a stock horse
Very good jumper
:)

Another one :)
