Transparent watercolor painted in a transparent manner. TWSA has recently utilized alternate selections due to final screening findings of heavy opacity. PLEASE, remember, regardless of what the pigment is rated, if you apply too many multiple washes, it can become opaque. Hold it up to natural light and if you see a shiny or leather-like appearance, it’s opaque.
