  2. Munsell color system - Wikipedia

    en.wikipedia.org/wiki/Munsell_color_system

    The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value ( lightness ), and chroma (color intensity).

  3. Universal indicator - Wikipedia

    en.wikipedia.org/wiki/Universal_indicator

    Universal indicator. A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution. [1]

  4. pH indicator - Wikipedia

    en.wikipedia.org/wiki/PH_indicator

    A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH ( acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1] Hence, a pH indicator is a chemical detector for hydronium ions (H 3 O +) or hydrogen ions (H +) in the ...

  5. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.

  6. Methyl orange - Wikipedia

    en.wikipedia.org/wiki/Methyl_orange

    Methyl orange is a pH indicator frequently used in titration because of its clear and distinct color variance at different pH values. Methyl orange shows red color in acidic medium and yellow color in basic medium. Because it changes color at the p Ka of a mid strength acid, it is usually used in titration of strong acids in weak bases that ...

  7. Shades of yellow - Wikipedia

    en.wikipedia.org/wiki/Shades_of_yellow

    Red, green and blue lights, representing the three basic additive primary colors of the RGB color system, red, green, and blue. Pure yellow light is composed of equal amount of red and green light. The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space.

  8. Shades of pink - Wikipedia

    CIELCh uv ( L, C, h) (84, 39, 1°) Source. HTML/CSS [1] B: Normalized to [0–255] (byte) Pink colors are usually light or desaturated shades of reds, roses, and magentas which are created on computer and television screens using the RGB color model and in printing with the CMYK color model. As such, it is an arbitrary classification of color.

  9. Orange (colour) - Wikipedia

    en.wikipedia.org/wiki/Orange_(colour)

    Orange is the colour between yellow and red on the spectrum of visible light. The human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary ...
