The first one is not DP, but the second one is :) If the first one was, it would say liver chestnut in the color name. The second one is, because it is red. If it did not have DP it would have been a more chocolate color.

@MakeMeABird So, a quick way to eliminate DP suspicion on chestnuts is if they have 2 Ssty genes but are not color named liver, they cannot have DP (this is what Maribo is refering to). DP is a darkening gene, along with Ssty and S+, and liver chestnut requires THREE darkening genes. So if there are already two on a non-liver chestnut (or a non-chocolate palomino), like with homozygous Ssty, then there can't be any DP. Bay, buckskin, and dun shades get weird, so it's worth it to look up examples.

Here's some helpful threads with examples and discussion of DP -

Shades of (Regular) Bay
DP in Wild Bays? Project
Examples of DP in bay and Buckskin

I bookmark them, personally, because I'm always needing to refer back to them :)
