The full range of 144 shades consists of a wide array of mono-pigmented colours. Specific traditional colours that have forged the reputation of the Sennelier brand have been retained, such as Madder Lake Deep and Genuine Cobalt Blue, the industry benchmark. Signature transparent colours, Chinese Orange and Cinnabar Green, for example, invented by Gustave Sennelier in conjunction with the Impressionists, have contributed significantly to the evolution of art styles.
