In this video (part 1 or 2), I use 3 primary watercolour paints to mix the 3 corresponding secondary colours using BlockX watercolours. I tint the colours with water and paint a value chart of the 6 colours. I demonstrate how to create a harmonious black that can then be diluted into grays useful for toning and shading. This video leads to a follow-up video (part 2) called “Painting Trees using a Monochromatic Colour Scheme.”
