Source. HTML Color Chart @30. B: Normalized to [0–255] (byte) In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel.
The fixed brightness settings correspond closely to these formulae to determine the RGB values: color1 := color × 100% color2 := color1 × 93.2% color3 := color1 × 80.4% color4 := color1 × 54.8%. Examples: "Yellow 2" (238, 238, 0) is based on "Yellow" (255, 255, 0) with 255 × 0.932 = 237.66.

Brown colors are dark or muted shades of reds, oranges, and yellows on the RGB and CMYK color schemes. In practice, browns are created by mixing two complementary colors from the RYB color scheme (combining all three primary colors).
The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.
Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet ( r, g, b ), each component of which can vary from zero to a defined maximum value.

In the RGB colour model, it is a tertiary colour. It is named after the fruit of the same name . The orange colour of many fruits and vegetables, such as carrots, pumpkins, sweet potatoes, and oranges, comes from carotenes, a type of photosynthetic pigment.
The IALA recommends categorical color codes in 7 colors: red, orange, yellow, green, blue, white & black. Adding redundant coding of luminosity and colorfulness adds information and increases speed and accuracy of color decoding tasks. [3]
The rg chromaticity space is used in computer vision applications, and shows the color of light (red, yellow, green, etc.), but not its intensity (dark, bright). LMS color space (long, medium, short), a perceptual color space based on the response functions of the cones in the retina of the eye.
