Complementary color:
Complementary colors those that are placed directly opposite each other on the color wheel, for example "red-green" or "yellow-purple". The opposing colors make for greater stability and contrast. Analogous colors: Generally, any three colors that are next to each other on the color wheel that go well together are known as analogous colors. For example, "blue" will go well with "blue-purple" and "blue-green". Monochromatic colors:
Monochromatics can be all one color, or different shades, tones or tints of one color.
A color wheel is used in conjunction with different color schemes to choose matching colors.
We select colors based on the mood we wish to convey: •Red: strong, aggressive, hot, angry, stimulating. •Blue: cold, clammy, depressing. •Yellow: light hearted, friendly, vivid. •Orange: warm, comforting, welcoming, energetic. •Green: cool, soothing, refreshing. Dark green also signifies wealth and masculinity. •Purple: luxurious, royal, sophisticated. •Bright: light, airy, liquid, relaxing. •Dark: dramatic, confined space, serious, rich. Then we find matching colors using various color schemes: •Complementary: use direct opposites on the color wheel, e.g. red & green. •Clash: use the color to the left or right of the complement, e.g. red & blue •Analogous: use 3 consecutive colors, e.g. red, red-orange & orange. •Monochromatic: use only different shades of the same color, just by varying its brightness, e.g. bright red, dark red. •Triads: use 3 equally spaced colors, e.g. red, blue & yellow, or green, purple & orange. Limit your main colors to 2 or 3 so as not to look like a patched-job, and stay consistent throughout the site.
