If you display a text with its complementary color on a background with the displayed color, you will get a representation that is pleasant to the eyes and clearly too indistinguishable from each other. However, this is especially true for white, black and gray tones. With these, the contrasting colors are particularly natural, pleasant and common for our eyes.

Richer colors are created by increasing the saturation, which makes the colors appear more intense, brighter and stronger. A color with high saturation is more eye-catching and appears more vibrant and powerful. This effect can be used to emphasize important elements or to create a vibrant design.

The #18C5E2 shade matches the following richer shades: #18C5E2 and #04D4F6

An example is the development from a pale pink to a strong and bright red.

Less saturated colors are created by reducing the saturation, which makes the colors more muted, subtle and pastel-like.

The following paler shades match the #18C5E2 shade: #18C5E2, #2CB7CE, #40A8BA, #549AA6 and #698B91

The following split-complementary shades match the #18C5E2 shade: #18C5E2, #5B18E2 and #E2AC18

This color scheme has the same strong visual contrast as the complementary color scheme, but is not as contrasting as the direct complementary color. The partial complementary color scheme is a good choice for designs. These colors usually complement each other very well.

A triadic color scheme uses colors evenly spaced around the color wheel. Triadic color harmonies are usually quite vivid, even if pale or unsaturated colors are used.

The following triaden shades match the #18C5E2 shade: #18C5E2, #E218C7 and #C7E218
