Brown is the second most common color of human hair, after black. It is caused by higher levels of the natural dark pigment eumelanin, and lower levels of the pale pigment pheomelanin. Brown eumelanin is more common among Europeans, while black eumelanin is more often found in the hair on non-Europeans.
I.e line and neutral are live conductors, but earth is not. Line (L; or phase line) A power-carrying conductor in a typical low-voltage or domestic installation. Colour-coded brown (pre-2004: red). Neutral (N) A power-carrying conductor in a typical low-voltage or domestic installation, usually bonded to Earth (ground) voltage by the supplier.
For power circuits, the color-coding uses the same colors as residential construction, and adds the additional wires used for three-phase systems. Black, Red and Blue are used for hot wires and White is used as the neutral wire in a 120/208 V circuit. Brown, Orange and Yellow are used as hot wires and gray is used as the neutral wire in a 277/ ...
In theory, such combinations should produce black, but produce brown because most commercially available blue pigments tend to be comparatively weaker; [citation needed] the stronger red and yellow colors prevail, thus creating the following tones. The color brown can also be made if multiple paint colors are added to each other.
Moving toward the central axis, colors become less and less saturated, until all colors meet at the central axis as a neutral gray. Moving vertically in the color solid, colors become lighter (toward the top) and darker (toward the bottom). At the upper pole, all hues meet in white; at the bottom pole, all hues meet in black.
The international standard IEC 60446 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors was a standard published by the International Electrotechnical Commission (IEC) that defined basic safety principles for identifying electrical conductors by colours or numerals, for example in ...
