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 ). Every wave of visible light is perceived as a spectral color; when viewed as a continuous spectrum, these colors are seen as ...
Eggplant is a dark purple [1] or brownish -purple [2] color that resembles the color of the outer skin of European eggplants. [3] Another name for the color eggplant is aubergine [2] (the French, German and British English word for eggplant). The first recorded use of eggplant as a color name in English was in 1915.
Metamerism (color) In column 1, a ball is illuminated by monochromatic light. Multiplying the spectrum by the cones' spectral sensitivity curves gives the response for each cone type. In column 2, metamerism is used to simulate the scene with blue, green and red LEDs, giving a similar response. In colorimetry, metamerism is a perceived matching ...
Tyrian purple (Ancient Greek: πορφύρα porphúra; Latin: purpura), also known as royal purple, imperial purple, or imperial dye, is a reddish-purple natural dye. The name Tyrian refers to Tyre, Lebanon , once Phoenicia .
Palatinate or palatinate purple is a purple colour associated with Durham University and the County and City of Durham. The term has been used to refer to a number of different shades of purple. The Oxford English Dictionary defines it as a "light purple or lavender colour", which is used for Durham (and Newcastle) academic hoods . [2]
Impossible color. The human eye's red-to-green and blue-to-yellow values of each one-wavelength visible color [citation needed] Human color sensation is defined by the sensitivity curves (shown here normalized) of the three kinds of cone cells: respectively the short-, medium- and long-wavelength types. Impossible colors are colors that do not ...
The CMYK color model (also known as process color, or four color) is a subtractive color model, based on the CMY color model, used in color printing, and is also used to describe the printing process itself. The abbreviation CMYK refers to the four ink plates used: c yan, m agenta, y ellow, and k ey (black).
The RGB color model, therefore, is a convenient means for representing color but is not directly based on the types of cones in the human eye. The peak response of human cone cells varies, even among individuals with so-called normal color vision; in some non-human species this polymorphic variation is even greater, and it may well be adaptive.
