Anyway, here's my latest enthusiasm: color wheels. I like the ones figured out by Color Wheel Basics. It's a series of wheels that emphasize tints and shades, and secondary and tertiary colors.
This interior decorators wheel (above) favors the kind of colors that were common a hundred years ago.
Here's (above) my most frequently used one.
New color wheels are always coming out. This Itten-type wheel looks like it would be fun to have on the wall but how does it work? Maybe it's not a wheel at all. Maybe it's just a nice pattern. I like the way that black sets off the other colors. Come to think of it, the wheel I said I use most often has plenty of black.
Here (above) are two that I just discovered. How the heck do they work?
This (above) is a color wheel that attributes flavors and aromas to the different colors. In this wheel tart and tangy are the complements of medicinal. I can't think of a use for this, but I'll bet it would have interested offbeat color theorists like Kandinsky.
