Which mare is what colour? lol

I have two chesnut mares that are quite different colours and am interested to hear how others would describe their respective colours??? Any feedback/input on the pics gratefully received. Left=Piper; Right=Sienna. Thanks.

Both sorrel/chestnut mares.
Not much else to tell you.
Both "red" horses.
Pics are not that great, but they both look cute, from what I can see.

A couple more pics.

Dark and light red. My mare is light in colour my wife's is darker.
Check it put at any interests, update weekly the first photo you see is Kate (half asleep) dark red chestnut. Look for Stella there is a southern flag in the photo. Stella is also a chestnut but light in colour. However, when the sun strikes her the colour is described as strawberry coloured. Her mane is even lighter, strawberry blond. I describe her as having a tarty look.

Both chestnuts. The one on the right in the last photo could use some serious groceries.

Both chestnut. Here in Australia you won't hear many people refer to them as sorrel. They are just different shades of the same colour

Yeah, she's 33 years young and gets serious groceries twice a day.

Age is not an excuse.

I think she is looking well for 33 yr old

Both sorrel. Genetically red/chestnut. If the old mare were mine I'd be doing bloodwork, getting her teeth floated, checking her fecal parasite counts, deworming if necessary, giving her free choice hay, senior feed, calorie boosts, etc. Old horses do not have to be thin.
