Here’s another color wheel added to my Art Journal. (You can see the previous one here. ) For the previous wheel I used opaque colors. This one was created using colors that are more transparent: Quinacridone Magenta, Pthalocyanine Blue (Green Shade) and Indian Yellow. The center ring is the pure paints mixed with each other. The outer ring is these mixtures with Titanium White and the inner ring is these colors mixed with Ivory Black.
I am surprised at how many artists do not keep an art journal/sketch book. I’ve used one for years, and I find that they are invaluable learning tools for me. I have recently started a new one, in a 12-inch by 9 inch, Bee, Super Deluxe Mixed Media Book . I really like these books because the paper is excellent. I can use it for pretty much any medium and it works well. I can also gesso the pages and paint directly on them.
