8- Green Watercolour Swatches
There are literally hundreds of artist quality watercolours available from many brands. I have tested many of them and created swatches as seen on the right. The square box is painted into a damp wash at the top to show the colour mixed in water, with more pigment added towards the bottom. The rectangle is painted in a juicy wash to show the mass-tone. The small squares at the bottom of the swatch have the pigment number and characteristics - staining, lightfast rating, granulation and transparency.
Single pigment Green Watercolours
Green pigments are denoted as PG followed by a number. Notice that Phthalo Green PG7 - a transparent, staining non-granulating green - is similar in hue to Viridian Green PG18, a transparent, non-staining granulating green. You can choose by colour and characteristics. Phthalo Green comes in GS (Green Shade) and YS (Yellow Shade). Note the section of Perylene Greens are made with PBk31, a Black pigment. The last section are all made with a yellow pigment PY129 - variations of Green Gold.
Greens made with Phthalo Green PG7 - staining and transparent
An unrealistic looking colour alone, this is a wonderful mixing colour. It makes an amazing range of useful greens with a warm yellow, Burnt Sienna, Indian Red and other earth pigments, and crimsons and reds. Also known as phthalo green blue shade. It is very similar from different manufacturers.
Greens Made with Phthalo Green PG36
Best known as phthalo green yellow shade. Another bright, unrealistic, mixing green, that is more on the yellow side.
Greens made with Chromium Green Oxide - PG17
This is an interesting opaque and granulating pigment.
Greens made with Viridian PG18 - granulating and liftable.
Although very similar in hue, Viridian is a much less powerful green in mixes than Phthalo Green. It is also granulating and non staining. It won't make the same wonderful blacks that can be created by mixing phthalo green with a crimson, bit it will make granulating colours that can be lifted out. It is a tricky pigment to make into a paint it seems, and may take a little more pre-wetting than most colours before use. I add a drop of glycerine to this in the palette and stir well to make rewetting easier.
Greens made with PBk31 - deep shadow greens
Greens made with PY129
Cobalt Green Watercolours - made from PG50
It is interesting that you'll also find PG50 colours in the turquoise section.
Single pigment greens in pigment number order. Includes PG8, PG23, PG26, and Daniel Smith Primateks.
Mixed Pigment Greens
Some are made from a yellow and a blue, some from a green and a yellow, some using earth pigments but all are mixed greens. It can be convenient to have a mixed green in your palette, especially if it is made with pigments already in your palette for the best colour harmony.
These swatches are painted and added as a guide. The intention is show the characteristics of each colour when painted. The colour reproduction is not perfect but hopefully will still be helpful used in conjunction with the manufacturer's website.
