Code grey: security needed, someone is unarmed, but is a threat to themselves or others. Code blue: life-threatening medical emergency. Code brown: external emergency (disaster, mass casualties etc.) Code orange: evacuation. Code purple: medical emergency. Code red: fire. Code yellow: internal emergency.
A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Grey value calculated from (0.2126 × red) + (0.7152 × green) + (0.0722 × blue) CIE L*a*b* values; sRGB value expressed as hue, saturation and lightness (HSL) device-independent CMYK value: cyan, magenta, yellow, black or key; LRV, but a consistent light reflectance value is not obtainable from pearlescent or metallic colours
25-pair color code chart used in certain kinds of wiring. A color code is a system for encoding and representing non-color information with colors to facilitate communication. This information tends to be categorical (representing unordered/qualitative categories) though may also be sequential (representing an ordered/quantitative variable).
The HSL and HSV model-builders took an RGB cube – with constituent amounts of red, green, and blue light in a color denoted R, G, B ∈ – and tilted it on its corner, so that black rested at the origin with white directly above it along the vertical axis, then measured the hue of the colors in the cube by their angle around that axis ...
Web colors are colors used in displaying web pages on the World Wide Web; they can be described by way of three methods: a color may be specified as an RGB triplet, in hexadecimal format (a hex triplet) or according to its common English name in some cases. A color tool or other graphics software is often used to generate color values.
RGB uses additive color mixing, because it describes what kind of light needs to be emitted to produce a given color. RGB stores individual values for red, green and blue. RGBA is RGB with an additional channel, alpha, to indicate transparency. Common color spaces based on the RGB model include sRGB, Adobe RGB, ProPhoto RGB, scRGB, and CIE RGB.
RGB color spaces are well-suited to describing the electronic display of color, such as computer monitors and color television. These devices often reproduce colours using an array of red, green, and blue phosphors agitated by a cathode ray tube (CRT), or an array of red, green, and blue LCDs lit by a backlight, and are therefore naturally ...
