Opus Resource Library

The six Professional Watercolours selected for 2024 are chosen from a range that offer extreme permanency to stand the test of time and all have a story based on heritage, history and contemporary use by great artists of today.

Venetian Red


An intense earth red. Unlike light red, which is yellower and Indian Red which is bluer, it is a distinct rich red favoured by Titian and originally sourced from quarries near Venice. Derived from the mineral hematite, variations in earth reds occur according to where the pigment comes from due to there being different concentrations of hematite in soil. Venetian Red is now a Synthetic Iron Oxide Red providing greater consistency of colour and texture. Also known as a caput mortuum.


Terre Verte


A beautiful delicate transparent green seen in frescoes and early Italian painting. Especially used in underpainting flesh tones – it provides cool half-tones which compliment later layers of warm reds and yellows, making the flesh more realistic. When layered and used in underpainting, beautiful greys can be achieved with its complimentary red. Valued over the centuries for its stabile, lightfast quality.


Cobalt Turquoise


Made with titanium dioxide and modern phthalo pigments, Cobalt Turquoise remains vibrant & clean in tints and mixes, creating beautiful greens and violets. It is great for painting a landscape to achieve a range of colour variation in foliage and is equally favoured by modern abstract artists such as Mark Rothko and Brice Marden, it is a colour full of possibility.


Magnesium Brown


A lightfast, opaque, moderately dark, iron zinc oxide with a unique caramel brown colour. Yellower than Burnt Sienna but warmer than an ochre, it provides a beautiful, warm granulation. It is distinct in its texture and shows the beauty of pigment over dyes or stains.


Lemon Yellow Deep


A deep lemon yellow, subtle in tone while also adding texture with its natural granular character to colours such as Manganese Blue and Rose Madder.


Cobalt Violet


A single pigment colour which is naturally super granular, a beautiful purple first discovered in 1859 by Salvétat. It is a semi-transparent and extremely permanent pigment possessing a delicate rose tinting strength.
