My sketch books have been busy!
Below is a colour wheel painted out in only single pigment colours. Some are not quite ideal, and not all are necessary, but an interesting exercise to do.
- Ultramarine Violet in the 5.30 position is very weak in Daniel Smith. Another brand may be better, though it is a weak tinting pigment. Try Da Vinci or perhaps QoR.
- Amethyst Genuine could go in the 5.30 spot instead, but is very dark and neutralised.
- Indanthrone Blue in the 4.30 position is also a neutralised blue.
- Cobalt Turquoise in 2.30 is not as bright and powerful as a mix of Phthalo blue and Phthalo green would be, and is more opaque and granulating but I love it! Amazonite genuine is a more transparent alternative.
- Cobalt Green in 1.30 would be better replaced with phthalo green YS.
- In the 11.30 position I have placed New Gamboge, but have mixed Quinacridone Gold below as that's my favourite warm yellow.
- Quin Rose in 7.30 could equally be Quin Magenta PR122. They are different but are both used as a cool clean mixing red for making purples.
Here they are painted out in pairs.
1 makes raw umber hues
6 Orange earth hues
8 Deep greens and greys
11 not so interesting.
I don't tend to work with a palette of pure bright colours as I love the earth pigments, but it's fascinating to see where they all fit into the palette.
