Description

In this Cohorts meeting, we will discuss why tints darken upon drying. Fresh tints that darken overnight can derail careful color-matching and shake your confidence at the easel. Conservation science now identifies two culprits—pigment-density packing and Marangoni flow—and demonstrates how straightforward studio adjustments can prevent them.
