  2. Holmgren's wool test - Wikipedia

    en.wikipedia.org/wiki/Holmgren's_wool_test

    In Holmgren's wool test, the patient is asked to match coloured skeins of yarn to the samples in the box. [6] [7] At first, the patient is asked to select from the 40 skeins, 10 skeins that best match the light green master A. [2] From the remaining 30 skeins, the patient is then asked to select the 5 skeins that best match the red master C. [2] Lastly, the patient is asked to select 5 skeins ...

  3. Metamerism (color) - Wikipedia

    en.wikipedia.org/wiki/Metamerism_(color)

    Color matches made in the paint industry are often aimed at achieving a spectral color match rather than just a tristimulus (metameric) color match under a given spectrum of light. A spectral color match attempts to give two colors the same spectral reflectance characteristic, making them a good metameric match with a low degree of metamerism ...

  4. LMS color space - Wikipedia

    The above development has the advantage of basing the new X F Y F Z F color matching functions on the physiologically-based LMS cone response functions. In addition, it offers a one-to-one relationship between the LMS chromaticity coordinates and the new X F Y F Z F chromaticity coordinates, which was not the case for the CIE 1931 color ...

  5. Anomaloscope - Wikipedia

    en.wikipedia.org/wiki/Anomaloscope

    Anomaloscope using a Rayleigh Match. An anomaloscope requires a subject to make a color match between a mixture color and a test color. The test color is a single spectral color, for which the subject can adjust the brightness. The mixture color combines two spectral colors, for which the subject can adjust the proportion, thereby changing the hue.

  6. Grassmann's laws (color science) - Wikipedia

    en.wikipedia.org/wiki/Grassmann's_laws_(color...

    Grassmann's laws describe empirical results about how the perception of mixtures of colored lights (i.e., lights that co-stimulate the same area on the retina) composed of different spectral power distributions can be algebraically related to one another in a color matching context.

  7. Colored music notation - Wikipedia

    Viewing color has been widely shown to change an individual's emotional state and stimulate neurons.The Lüscher color test observes from experiments that when individuals are required to contemplate pure red for varying lengths of time, [the experiments] have shown that this color decidedly has a stimulating effect on the nervous system; blood pressure increases, and respiration rate and ...
