What colour is she?

I was wondering what colour my yearling is. I can't quite figure out if she's bay or something else because of her white socks. The second picture is more what she looks like in natural lighting.

I will guess brown because you say the second photo is more accurate. It's really hard to tell from these photos though.

She looks like a light bay?

Yeah I know. My camera sucks and the sun was going down. I figured she is brown after reading some other posts on here. Thanks!

If she is brown with black points (mane, tail, legs) then she is bay.

Brown horses can have black points. This filly looks like a brown to me - she is still coming into her adult coat though, and it will become clearer as time goes on.

In my area, a brown (all shades of brown whether red or true brown) horse with black points is a bay. Apparently it depends on the breed whether you call it bay or brown.
Terms could also be different in different locations.

"Some breed registries (including the Jockey Club Thoroughbred registry) use the term "brown" to describe dark bays."

I think brown too. Her mane & tail don't look black to me... unless they're very sun-faded?

Celeste, brown & bay are genetically different colours. They are both caused by different varieties of the agouti gene.

While this used to be the case, since using the term 'brown' went out of fashion, as Quixotic said, they have now isolated the gene that causes brown. On a genetic level, the horse is different. It is no longer a location thing, like sorrel and chestnut still is. Sorrel and chestnut are genetically the same - bay and brown are not.
