So what do these color combinations look like when they are put into practice?
Notice that when you add the colors directly beside GREEN on the color wheel for the ANALAGOUS color scheme it creates interest and depth as compared to just using the shades and tints of the MONOCHROMATIC color scheme.
By adding a little bit of VIOLET to the RED in the SIDE-COMPLEMENTARY the picture is heightened.
Adding the 3rd leg color of RED-ORANGE to the SPLIT-COMPLEMENTARY color scheme, introduces warm and cool tones of the BLUE.
PENTAGONAL takes this a step further with adding even more dimension with the warm YELLOW & cool BLUE. (see my blog post discussion of the importance of warm & cool colors in What is Color Temperature and Why Is It So Important.)
These two color schemes are all about balance.
Using just ORANGE & GREEN feels unbalanced until you add the 3rd leg of PURPLE.
Whereas in the SQUARE-TETRADIC color scheme, GREEN’s COMPLEMENTARY is equally balanced with the COMPLEMENTARY of BLUE-VIOLET.
In the last color scheme, a different set of COMPLEMENTARY colors (ORANGE/BLUE) balances the GREEN COMPLEMENTARY for a slightly different feel.
Interestingly, the GREEN COMPLEMENTARY color scheme will be interchangeable with the RED COMPLEMENTARY color scheme. The only difference will be the importance given to GREEN.
The same is true for GREEN SQUARE-TETRADIC and RED SQUARE-TETRADIC.
Similarly, GREEN TRIADIC will be the same as VIOLET TRIADIC and ORANGE TRIADIC. The only difference being the importance put to the focus color.
