This is a watercolor demo step by step, using just two colors: French Ultramarine Blue + Burnt Sienna.
Painting is done mostly wet on wet.
This shows the importance of tonal value over color.

This video was filmed during a workshop by Alvaro Castagnet at Budapest.
Every concept exposed during the painting is to record in your mind and keep some time to think about it.
This is just 9 minutes length but worth it.
