An electronic color-chart device includes plural LEDs with different peak wavelengths and displays images to serve as color references as color charts by making the plural LEDs emit light. In a case where a light emission intensity distribution of each of the plural LEDs is normalized with a ...

Each type of cone is sensitive to a particular wavelength band and possesses unique sensitivity levels, forming what is known as a tristimulus response. Therefore, the human eye may perceive light with the same intensity as having different intensities. This must be considered during the color ...
Color theory refers to the rules and science behind color, including how humans perceive color and how colors visually mix with and contrast. The color wheel is at the foundation of color theory. This wheel acts as a visual representation of colors, arranging them according to wavelength. C...
Hue refers to the dominant wavelength of color, saturation refers to the purity of its hue, and luminance refers to its lightness or darkness.As with all colors, colors defined with the HSL color model can have color transforms applied to it....

So when thinking about how to color your brand, it’s worth considering which major brands use which colors because those brands lay dormant in the associative recesses of the client’s subconscious. Check out the chart below to see some of the major brand associations of each color. ...
“Color Gamut” of a fireworks show, plotted in CIE 1976 (u’v’) with comparison to HDTV and BT.2020 color gamuts. Colors that lie outside the HD TV region in the above chart cannot be accurately displayed by an HD set. These TVs distort what you see by remapping deeply saturated c...
Generally, males required a slightly longer wavelength to experience the same hue as did females. The spectral loci of the unique hues are not correlated with anomaloscope matches; these matches are directly determined by the spectral sensitivities of L- and M-cones (genes for these cones are ...
The test chart is scanned and measured using the HP Embedded Spectrophotometer. From the measurements made by the spectrophotometer, the printer calculates the necessary correction factors to apply for consistent color printing on that paper type. It also calculates the maximum amount of each ink that...
