In case anyone is curious here are my top color recommendations
Handprint.com is hands down the most comprehensive scientific explanation of how different color wheels or palette choices work. It's big and dense and exceptionally thorough. I skim frequently and find myself always learning more. https://handprint.com/HP/WCL/water.html everything is done using watercolors as a reference point but a LOT of this translates to other mediums. For the record his CIECAM color wheel is what I consider to be the best (not 3 dimensional) color wheel for artists. Period.
He uses pigment numbers for some of the most common watercolors rather than specific paint brands or color names to place the pigments. It's also a case study in why yellow being at the top is the best because it also means you have a value scale from top to bottom (since black paints are just dark violets or blues, ultimately.)
When you look at this, you can start realizing more and more why the earth colors can be used as if they were like, straight red, or yellow, or orange. Like if you wanted to make a limited palette, you could use "burnt sienna" as your dark yellow (which will make the whole palette lean orange!) Or it could be your orange or you could use burnt sienna as your red. (Look at gamut masking links below)
Seriously it's good to try and swatch your medium (even really quickly!) Within a CIECAM Artist's color wheel. Below are two of my attempts:
From loose memory and then mapping pigments roughly.
He also discusses the difference between visual complements and mixing complements!
Anyways absolutely try to read bits and pieces. The whole site is amazing. Handprint is amazing.
https://gurneyjourney.blogspot.com and James Gurney's book: Color and Light: a guide for the realist painter. James Gurney is the dinotopia guy. That book is also amazing for painting fantasy with lots of fantastical examples. Here are two short videos on gamut mapping and gamut masking. Accompanying blog posts.
No surprises here! His book also charts pigments:
Actually these are my four favorite books hands down:
Color and Light: a Guide for the realist painter - James Gurney
Color for Painters: a guide to traditions & practice - Al Gury
The oil painters color handbook - Todd m casey
Artist's master series: Color & light - 3d total publishing. This one emphasizes digital!
The first two have been out for awhile now and you can more easily find them cheaper/used online than the latter two which are relatively newer and hefty hardbacks.
Also, from personal experience: al gury is a sweetheart angel who is a huge crazy cat man. I adore him, he's so kind and helpful. I think it's a little late to join the current session (although they did only start Jan 28, so you can always ask! Class videos are recorded), BUT he frequently offers a class on color that is fully online through PAFA continuing education, as well as other classes. I haven't taken it yet, but I HAVE taken other classes online with Al and he's really great.
Oh also online gamut masking tools:
In krita: https://docs.krita.org/en/user_manual/gamut_masks.html
https://claudiamatosa.com/resources/gamut-masking simple tool
https://mypaintingclub.com/blog/post/39-The-Gamut-Mask-Tool another tool with more complexity
The tl;Dr of a gamut mask is to show you the full range of possible colors you can mix within a given palette (choices of colors/pigments).
