Metamerism occurs because each type of cone responds to the cumulative energy from a broad range of wavelengths, so that different combinations of light across all wavelengths can produce an equivalent receptor response and the same tristimulus values or color sensation.
In optics, the Kubelka–Munk theory devised by Paul Kubelka [1] [2] and Franz Munk, is a fundamental approach to modelling the appearance of paint films. As published in 1931, [3] the theory addresses "the question of how the color of a substrate is changed by the application of a coat of paint of specified composition and thickness, and especially the thickness of paint needed to obscure the ...
Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
A rainbow is a decomposition of white light into all of the spectral colors. Laser beams are monochromatic light, thereby exhibiting spectral colors. A spectral color is a color that is evoked by monochromatic light, i.e. either a spectral line with a single wavelength or frequency of light in the visible spectrum, or a relatively narrow spectral band (e.g. lasers).

Light spectrum, from Theory of Colours – Goethe observed that colour arises at the edges, and the spectrum occurs where these coloured edges overlap.. Theory of Colours (German: Zur Farbenlehre) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how they are perceived by humans.
The problem for the MSX 1 was that many European software companies who converted Spectrum games to MSX 1 ignored all the improvements the MSX 1 had over the Spectrum, and thus the resulting MSX 1 versions had the same amount of attribute clash as the original Spectrum games (Jack the Nipper II: In Coconut Capers is one example of this). To ...
