The beauty of Yellow – Cadmium Lemon, Cadmium Yellow Light, Cadmium Yellow Medium

Cadmium Lemon Yellow is a bright, tangy colour, which is prepared using a light lemon (almost green shade) that is mixed with crystal inorganic pigment, cadmium zinc sulphide. This inorganic pigment can lighten and increase the opacity of mixing warm colours without overthrowing them. The pigments also has excellent heat stability, and a high degree of light fastness which makes it ideal to use in a professional watercolour range. When used on the artists’ palette, the colour is often used as cool primary colour. It is also opaque and retains its strong, vibrant colour when diluted.

Cadmium Yellow pigments where first founded in the early 19th century but the early forms often darkened when exposure to light and air. Later, another cadmium based pigment was founded using cadmium sulphide and zine sulphide, which formed a stronger and stable pigment. These pigments are bright and have a good transparency when used in thin washes. The pigments have an excellent heat stability, a high degree of light fastness and also chemical resistance. When used on the artists’ palette it can be used as a mid-shade yellow, which can be mixed with blue to form a selection of greens or with red to form a selection of oranges.
