Viridian Hue (W261)andnbsp;Vert andEacute;meraude Imit.

Phthalo Green (organic) is a transparent, cool, bright, high intensity colour used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. It has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base colour for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colours in various tints. However, its tinting strength is very high, so it can overpower other colours. This pigment most closely resembles the discontinued and toxic Verdigris.

Historically, this bright blue-green was developed in 1935 and has been in use since 1938.
