Why does sap green look different when acrylic dries?

Acrylic binder looks milky while wet and clears as it dries, so the dried film reads darker. Chromilla's model applies a 10% value shift for acrylic, so the wet mix #506C28 is predicted to dry to about #4B6122. Dries slightly darker and a touch warmer.
