Quoted from Pocket Color Wheel

The Artistic Color wheel is based on the primary colors Red, Yellow and Blue.

Here's some visuals for every color category. The numbers on the left are the values and at the bottom is the chroma/saturation. One reason I find these images helpful is being able to see the value of a color at full saturation. For example yellow has a very high value and makes a good color to lighten other colors rather then using just white. These charts also make it clear what the difference is between value and chroma/saturation.

Yellow-Green

Judy, I'm glad you like it! The RYB color wheel is what I started with and studied many different color wheels after but ended up doing a full circle and coming back to this one.

Please disregard the color designations 2Y etc at the botton of the sheets as they're from a Munsell programme. Munsell differs greatly from RYB color wheel. The colors I slected for each color category on these are the ones that match the RYB color wheel.
