The monochromatic color scheme uses variations in lightness and saturation of a single color. This scheme looks clean and elegant. Monochromatic colors go well together, producing a soothing effect. The monochromatic scheme is very easy on the eyes, especially with blue or green hues. You can use it to establish an overall mood. The primary color can be integrated with neutral colors such as black, white, or gray. However, it can be difficult, when using this scheme, to highlight the most important elements.
Pros: The monochromatic scheme is easy to manage, and always looks balanced and visually appealing.
Cons: This scheme lacks color contrast. It is not as vibrant as the complementary scheme.
The analogous color scheme uses colors that are adjacent to each other on the color wheel. One color is used as a dominant color while others are used to enrich the scheme. The analogous scheme is similar to the monochromatic one, but offers more nuances.
Pros: The analogous color scheme is as easy to create as the monochromatic, but looks richer.
Cons: The analogous color scheme lacks color contrast. It is not as vibrant as the complementary scheme.
