Choose colours lemon yellow, ultramarine blue, burnt sienna, raw sienna, madder lake. This composition uses wet-in-wet and dry brush techniques. Don't forget wet-in-wet needs the paper really wet and your paint will be diluted by the water - never paint to the edge of the wet part you will get a strong line. It's recommended to mix up your paint before wetting the paper!
