Hooker’s Green
William Jackson Hooker was an English botanist and botanical illustrator who lived from 1785 to 1865. In his botanical illustrations, he naturally needed a natural green color for all green plants. He liked to use a mixture of Prussian blue and gamboge for this.
This color mix eventually became a classic and was named hookers green. Later, the fugitive gamboge was replaced by the slightly more durable aureolin and over time, the color became common among the paint manufacturers as a ready-mixed “natural green”.
Hooker’s green is a classic color mix that all manufacturers of watercolor paint have in their range, several have the color in different variants with additions to the name such as light, deep, dark.
Not a single manufacturer uses the original mixture of Prussian blue + some yellow, pretty much everyone uses phthalo green + some (warm) yellow, some mix in red or black to make the mixture darker. There are those who use the same pigment for different variants, Rembrandt and Da Vinci use for example phthalo green (BS) + Rembrandt Nickel Azo yellow and Da Vinci synthetic iron oxide in both “light” and “deep” with a little more yellow in the light, As a consumer, you must feel cheated if you use both. Others, like Maimeriblu, just take a green color (chromium oxide green) and call it Hooker’s Green, so does Shinhan with another pigment.
It seems that anything that is greenish can be called Hooker’s Green, even chromium oxide green. I recommend that you mix your natural green yourself, use a blue color that does not granulate, e.g. Prussian blue, phthalo or indantron and mix it with any yellow, I myself would use Nickel Azo which is warm and transparent. If you want to make the color darker, mix in a little cold red, e.g. quinacridone rose or Alizarin.
Here is a list of the major manufacturers’ different Hookers Green, they are very different and have different recipes for the mixes. Note that PG7 and PG36 are common, they are the two phthalo green pigments.

Very interesting article. As far as I’m concerned, I’ll mix phthalo blue with nickel azo yellow as you suggest. Nickel Azo is my preferred yellow
This is a very interesting post; thank you for writing it. I always enjoy reading your posts.
I must disagree on one point, though: there is actually one manufacturer who mixes Hooker’s Green using as close a combination to the original as modern pigments allow: Roman Szmal (pronounced Shmal). Roman Szmal’s Hooker’s green is made of PB27 and PY150 (Prussian Blue + Nickel Azo Yellow). I think Nickel Azo Yellow is as close to genuine Gamboge as a single pigment can get. I think Nickel Azo Yellow has the same vividness as Gamboge.
Interesting, so there is a manufacturer who is faithful to the original mix. Roman Szmal’s colors are unusual in Sweden, I forget that they exist.
Oh, interesting. I always thought Hooker’s Green is PG8, which is a lovely natural green. I was wrong. I do love Prussian Blue for mixing greens.
Which manufacturer uses PG8 today? Is there anyone? I thought the pigment was relegated to the archive for abandoned pigments.
St Petersburg White Nights still use PG8 as their plain Green
And that’s not the only fugitive pigment they use.
Well, Prussian blue is also fugitive, so I guess it doesn’t really matter which one you use. White Nights and Rosa Gallery both have PG8.
