Graham for example, rather than the PR101 hue by Winsor and Newton. My preference is for the PBr7 versions made by Da Vinci, Daniel Smith and M. Many brands are made using alternative colours, so are called a hue, but Old Holland makes the genuine article and it is famous for painting shadows in snow.īurnt Sienna, one of the most useful colours on the palette after the primaries, comes in a huge range of forms from an earthy orange-brown to a transparent burnt orange, and can be made from PBr7, PR101 and a whole host of other hues. A highly granulating cool but light blue is Manganese Blue (genuine) made with PB33. ![]() Phthalo blue comes in Red Shade and Green Shade from many manufacturers and is a useful mixing blue. If a non-granulating blue is required, Indanthrone blue (PB60) or Phthalo blue (PB15) may be the better choice. Granulating Ultramarine can be lovely for greens in foliage, browns, neutrals and skies. Ultramarine will granulate to some degree in almost any brand, though less with Schmincke Ultramarine Finest. Since I paint a lot of landscapes, I love the granulating pigments. It can be useful to have an opaque cadmium yellow for the same reason. It can be useful to mix a green that will cover other greens, especially if mixed with Yellow Ochre. Cerulean is another semi-opaque and granulating watercolour if made with PB35 or PB36. There are some exceptions though, for example, I use Indian Red (PR101) which is generally opaque. It is very personal. My preference is for largely transparent watercolours, so I generally don't choose cadmiums or cobalts but transparent alternatives. What you want is a range of warm and cool, transparent and opaque, granulating and not, staining and liftable paints that suit your subject matter and style. Some are considered semi-transparent or semi-opaque. ![]() They are more enjoyable and easier to use! Generally, earth pigments are likely to be granulating, Phthalo pigments are transparent and staining, Cobalt pigments are opaque and lift easily, Cadmiums are opaque, Pyrrols are more transparent. You can also look up pigments on the fabulous Color of Art Pigment Data Base or on 's Guide to Watercolor Pigments Series numberĮven if you are a beginner, buy artist quality watercolours rather than student grade. However you can see watercolours arranged by pigment numbers in the Painted Watercolour Swatches section of this website. You can see much more on specific pigments on my blog such as PB29 and this on on PV19 and one on a range of blue pigments here. Sometimes there is a further number, so PB15 is phthalo blue, but PB15:3 is the Green Shade, PB15:6 is the Red Shade. PW = Pigment White Eg Titanium White is PW6. ![]() However, the one pigment number may have many varied versions. Pigment numbers are really helpful to translate colours from one medium to another - for example if you like a colour in oils and want to find it in watercolour, the pigment number may be helpful. If there are two or more they are a mixed pigment paint. If there is just one pigment number they are single pigment paints. Paints should be labelled with the pigment number to show what they are made from.
