Rosemary primarily works in watercolour. Her vibrant, translucent paintings echo her interest in complex patterns of shape, light, colour and texture. Being inspired by the unusual viewpoint or subject matter, she works with a limited palette allowing the painting to evolve using many layers of wet into wet pure watercolour. This gives a unity and living colour throughout her wide range of subject matter.
Besides working in her studio with the many photographs and sketches gathered on location the she enjoys the challenges and excitement of painting ‘en plein air’. More recently Rosemary has been exploring other media particularly oils exploring its immediacy and mark making qualities.
