How to adjust metallic watercolor

Quick answer：

Adjusting the metallic watercolor involves mixing it with a binder, usually a small amount of gel medium, to improve flow and adhesion. To do this, mix the watercolor with the binder in a 1:1 ratio, stirring well until fully combined. This will create a more fluid consistency suitable for metallic effects. Remember to test on a small area first to ensure the color and metallic sheen meet your expectations.
