Complementation

Explanation:

     The main point in combining colors is to see if they are complementary or contrasting, because that's what makes them match in the end. Simply put, this means that colors have to make sense when mixed, either because they highlight each other or because they complement each other. To find out if this happens, we can start by looking at whether they are different or similar colors.

    Complementary colors are those that, within the color circle, are positioned opposite each other. In general, they serve to decrease the intensity of the colors and obtain neutral or gray colors when mixed. They also show greater contrast to each other and absorb their spectra more.

    If the two colors are quite different, that is, of course contrast with each other, they can be used simultaneously, as they will not fight each other. However, in order to create harmony in the environment, it is important that at least one or both of them repeat in the environment at different points to maintain balance and integration.

    If the colors are similar, they will only match if they are the same shade, only lighter or darker than the other, or if one is very soft and the other very vivid and intense. It is not cool, for example, to use a bright, bright pink with a bright, bright orange, as these two blended colors are not different enough to contrast or similar enough to complement each other.
