Color codes on electron

The electronic color code discussed here is used to indicate the values or ratings of electronic components, very commonly for resistors, but also for capacitors, inductors, and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Colorbands were commonly used (especially on resistors) because they were easily printed on tiny components, decreasing construction costs. However, there were drawbacks, especially for color blind people. Overheating of a component, or dirt accumulation, may make it impossible to distinguish brown from red from orange. Advances in printing technology have made printed numbers practical for small components, which are often foun The standard color code per EN 60062:2005 is as follows: Color Significant figures Multiplier Tolerance Temp. Coefficient (ppm/K)
1.Black 0 ×100 – 250 U 2.Brown 1 ×101 ±1% F 100 S 3.Red 2 ×102 ±2% G 50 R 4.Orange 3 ×103 – 15 P 5.Yellow 4 ×104 – 25 Q 6.Green 5 ×105 ±0.5% D 20 Z Blue 6 ×106 ±0.25% C 10 Z 7.Violet 7 ×107 ±0.1% B 5 M 8.Gray 8 ×108 ±0.05% A 1 K 9.White 9 ×109 – – 10.Gold – ×10-1 ±5% J – 11.Silver – ×10-2 ±10% K – 12.None – – ±20% M – d in modern electronics.

Traffic light on color

Traffic lights, which may also be known as stoplights, traffic lamps, traffic signals, stop-and-go lights, robots or semaphore, are signaling devices positioned at road intersections, pedestrian crossings and other locations to control competing flows of traffic. Traffic lights have been installed in most cities around the world. They assign the right of way to road users by the use of lights in standard colors (Red - Amber - Green), using a universal color code (and a precise sequence, for those who are color blind). Typically traffic lights consist of a set of three colored lights: red, amber and green. In a typical cycle, • Illumination of the green light allows traffic to proceed in the direction denoted, • Illumination of the amber light denoting if safe to, prepare to stop short of the intersection, and • Illumination of the red signal prohibits any traffic from proceeding. Usually, the red light contains some orange in its hue, and the green light contains some blue, to provide some support for people with red-green color blindness

Color codes of fire extinguishers

A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e. no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire department. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discha nternationally there are several accepted classification methods for hand-held fire extinguishers. Each classification is useful in fighting fires with a particular group of fuel.

Color code on optical Fibre

The buffer or jacket on patchcords is often color-coded to indicate the type of fiber used. The strain relief "boot" that protects the fiber from bending at a connector is color-coded to indicate the type of connection. Connectors with a plastic shell (such as SC connectors) typically use a color-coded shell. Standard color codings for jackets and boots (or connector shells) are shown below: Buffer/jacket color Meaning:
1.Yellow single-mode optical fiber 2.Orange multi-mode optical fiber 3.Aqua 10 gig laser-optimized 50/125 micrometer multi-mode optical fiber
4.Grey outdated color code for multi-mode optical fiber 5.Blue Sometimes used to designate polarization-maintaining optical fiber

Colors Codes on 3D

Complementary color anagrams employ one of a pair of complementary color filters for each eye. The most common color filters used are red and cyan. Employing tristimulus theory, the eye is sensitive to three primary colors, red, green, and blue. The red filter admits only red, while the cyan filter blocks red, passing blue and green (the combination of blue and green is perceived as cyan). If a paper viewer containing red and cyan filters is folded so that light passes through both, the image will appear black. Another recently introduced form employs blue and yellow filters. (Yellow is the color perceived when both red and green light passes through the filter.). Scientific images where depth perception is useful include, for instance, the presentation of complex multi-dimensional data sets and stereographic images of the surface of Mars. With the recent release of 3D DVDs, they are more commonly being used for entertainment. Anaglyph images are much easier to view than either parallel sighting or crossed eye stereo grams, although these types do offer more bright and accurate color rendering, most particularly in the red component, which is commonly muted or desaturated with even the best color anaglyphs. A compensating technique, commonly known as Anachrome, uses a slightly more transparent cyan filter in the patented glasses associated with the technique. Processing reconfigures the typical anaglyph image to have less parallax to obtain a more useful image when viewed without filters.

Identification by color

HMIS (Hazardous Materials Identification System) is a numerical hazard rating that incorporates the use of labels with color-coded bars as well as training materials. It was developed by the National Paint & Coatings Association (NPCA) as a compliance aid for the OSHA Hazard Communication Standard. The HMIS Color Bar is similar to the fire diamond, created by the National Fire Protection Association. Before 2002 the fire diamond and the color bar both had sections colored blue, red, white, and yellow. After April 2002, with the release of HMIS III, yellow in the color bar (which stood for reactivity) was replaced by orange, standing for physical hazard. The fire diamond is designed for emergencies when information about the effects of short, or acute, exposure is needed. The color bar is not for emergencies and is used to convey broader health warning information. The four bars are color coded, using the modern color bar symbols with blue indicating the level of health hazard, red for flammability, orange for a physical hazard, and white for Personal Protection. The number ratings range from 0-4.

Life Style and Color

A lifestyle is a characteristic bundle of behaviors that makes sense to both others and oneself in a given time and place, including social relations, consumption, entertainment, and dress. The behaviors and practices within lifestyles are a mixture of habits, conventional ways of doing things, and reasoned actions. A lifestyle typically also reflects an individual's attitudes, values or worldview. Therefore, a lifestyle is a means of forging a sense of self and to create cultural symbols that resonate with personal identity. In every style there is some personality shapes of color which make one life style perfect.
