In colouristics there are several methods for constructing a color palette (color gamma) based on the arrangement of colors relative to each other in the color circle. Harmonious combination of which is not justified from a physical point of view. The wave method of building color palette, developed by us, based on the relationship of color and acoustic waves, and also the concept of consonance (harmony) in music theory. Acoustically, the essence of the difference between consonance and dissonance is expressed in different lengths of periods of regularly repeated groups of oscillations. The criterion of the difference between consonance and dissonance is the simplicity or complexity of the relationship: simpler relationship is more consonant, more difficult is more dissonant. Just as chords sound harmonious in music, colors in a picture look harmonious as well. For practical use we made website with color picker — https://wavepalette.com/. Perfect consonances are taken as a basis: a pure fourth (a chord of notes Do and Sol), a pure fifth (a chord of notes Do and Fa). Three systems are used for construction - sRGB (white point D65), CIE XYZ and HSL, as well as tables containing wavelengths of visible light - CIE 1931 2-deg (XYZ CMFs). This picker allows you to match the most harmonious colors to the base color, which you can choose by setting wavelength, saturation and lightness.
