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 and, usually, having the same brightness. Harmonious perception of which is not sufficiently substantiated from the physical point of view. The wave method of building color palette based on the relationship of color and acoustic waves, and also the concept of consonance (harmony) in music theory. More detailed description of the method is here - https://wavepalette.com/about/ https://wavepalette.com/about/ A few days ago, the algorithm was completely finalized and posted on the site - https://wavepalette.com/ https://wavepalette.com/. There is also a mobile application and ready-made palettes - https://wavepalette.com/palettes/ https://wavepalette.com/palettes/

I don’t understand this. Light wavelength and perceived color aren’t directly related — just look at the hue color wheel in any painting app, and you can see there’s a great “spectrum wasteland” of very similar blue-greens, while many aesthetically interesting variations of yellows and oranges are within a very narrow range. How does this harmonics model take those perceptual biases into account? The examples on the site are not convincing. They bring to mind the palettes used in IBM’s ancient CGA hardware: https://wavepalette.com/palettes/ https://wavepalette.com/palettes/

  In 1926-1930 Wright and Guild conducted experiments on 15 independent observers. They compared the spectral color with a specific wavelength to a mixture of red (700 nm.), blue (435.8 nm.) and green (546.1 nm.). In 1931 the International Lighting Congress (CIE) adopted a characteristic of the color properties of the average (standard) observer, based on this results. Later, for comfort calculations, the International Lighting Congress introduced the abstract system CIE XYZ, based on unreal colors. This coordinate system is very comfort for the transition from one system to another. Also, the wavelengths of visible light and the corresponding coordinates of the CIE XYZ mixture were calculated, based on the results obtained for the RGB system (Wright and Guild). sRGB system of monitors have many non-spectral colors. The wave method is applied in this case (on "RGB" site page) to each of the three colors (red, green, blue) individually, not all colors are harmonious and you will have to make a choice manually. This method allows you to get more interesting combinations of colors, but requires a self-dependent choice.
