Michael Harding Artists Oil Colours - Viridian (No. 511) - 40ml

Inorganic – Viridian is about the fastest curing colour in the entire Michael Harding range, along with Stack Lead White. This hydrated variant of Chromium Hydroxide, introduced in the mid-19th century, is a valued support colour used for influencing greys in underpainting. The vivid blue undertones apparent in thin layers are soon eclipsed in thicker applications. Landscapists and some portraitists still prefer it to the more brutal power of the Phthalo Greens. When combined with reds, an interesting range of blue-greys results. Placing it as local colour in the proximity of vermilion can also produce some interesting complementary effects.
