  2. Color vision - Wikipedia

    en.wikipedia.org/wiki/Color_vision

    Thus color information is mostly taken in at the fovea. Humans have poor color perception in their peripheral vision, and much of the color we see in our periphery may be filled in by what our brains expect to be there on the basis of context and memories. However, our accuracy of color perception in the periphery increases with the size of ...

  3. Color - Wikipedia

    en.wikipedia.org/wiki/Color

    Colored pencils. Color (or colour in Commonwealth English; see spelling differences) is the visual perception based on the electromagnetic spectrum.Though color is not an inherent property of matter, color perception is related to an object's light absorption, reflection, emission spectra, and interference.

  4. Linguistic relativity and the color naming debate - Wikipedia

    en.wikipedia.org/wiki/Linguistic_relativity_and...

    The color spectrum clearly exists at a physical level of wavelengths (inter al.), humans cross-linguistically tend to react most saliently to the primary color terms (a primary motive of Bornstein's work and vision science generally) as well as select similar exemplars of these primary color terms, and lastly comes the process of linguistic ...

  5. Tetrachromacy - Wikipedia

    en.wikipedia.org/wiki/Tetrachromacy

    The four pigments in a bird's cone cells (in this example, estrildid finches) extend the range of color vision into the ultraviolet. [1]Tetrachromacy (from Greek tetra, meaning "four" and chroma, meaning "color") is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cell in the eye.

  6. Color appearance model - Wikipedia

    en.wikipedia.org/wiki/Color_appearance_model

    A uniform color space (UCS) is a color model that seeks to make the color-making attributes perceptually uniform, i.e. identical spatial distance between two colors equals identical amount of perceived color difference. A CAM under a fixed viewing condition results in a UCS; a UCS with a modeling of variable viewing conditions results in a CAM.

  7. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment.

  8. Colorimetry - Wikipedia

    en.wikipedia.org/wiki/Colorimetry

    Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.

  9. On Vision and Colours - Wikipedia

    en.wikipedia.org/wiki/On_Vision_and_Colours

    Before discussing color, there are some preliminary remarks to be made regarding vision. In § 1, it is shown that the perception of externally perceived objects in space is a product of the intellect's understanding after it has been stimulated by sensation from the sense organs.
