This was more challenging than I'd thought it be. Being restricted to certain colors is hard!
But I hope you like these :)
I chose to do the normal mode.
01-05: MONOCHROMATIC - a single hue with different shades
06-10: ANALOGOUS - colors next to each other on the wheel; a primary color and its various shades
11-15: COMPLEMENTARY- 2 colors opposite to each other on the color wheel
16-20: TRIADIC - colors that are evenly spaced around the color wheel
If you take any, please credit naginis or accios.
