So I have fallen in love with the Dark Liver color on horses...unfortunately I have not been able to produce this coat with any breedings, even from my darkies...so I did see it was possible to achieve with two brown coats and a red dun coat combined with a brown...does anyone have a chart or recommendations for how to breed this color coat? Thanks!

Liver Chestnut and dark flaxen liver chestnut are just coat variants of chestnut (red based) horses. You can reroll chestnuts to get one or attempt to breed one using two red based horses (ee), but rerolls are likely your best bet.

Thank you!!
