Cyan is a greenish-blue color. It is evoked by light with a predominant wavelength of between 490–520 nm, between the wavelengths of green and blue. In the subtractive color system, or CMYK, which can be overlaid to produce all colors in paint and color printing, cyan is one of the primary colors, along with magenta and black. In the additive color system, or RGB color model, used to create all the colors on a computer or television display, cyan is made by mixing equal amounts of green and light blue. Cyan is the complement of red. Mixing red light and cyan light at the right intensity will make white light; the web color cyan is synonymous with aqua. Other colors in the cyan color range are teal, electric blue and others described as blue-green, its name is derived from the Ancient Greek κύανος, transliterated kyanos, meaning "dark blue, dark blue enamel, Lapis lazuli". It was known as "cyan blue" or cyan-blue, its first recorded use as a color name in English was in 1879. Further origins of the color name can be traced back to a dye produced from the cornflower.

In most languages,'cyan' is not a basic color term and it phenomenologically appears as a greenish vibrant hue of blue to most English speakers. Other English terms for this "borderline" hue region include blue green and turquoise; the web color cyan shown at right is a secondary color in the RGB color model, which uses combinations of red and blue light to create all the colors on computer and television displays. In X11 colors, this color is called both aqua. In the HTML color list, this same color is called aqua; the web colors are more vivid than the cyan used in the CMYK color system, the web colors cannot be reproduced on a printed page. To reproduce the web color cyan in inks, it is necessary to add some white ink to the printer's cyan below, so when it is reproduced in printing, it is not a primary subtractive color, it is called aqua because it is a color associated with water, such as the appearance of the water at a tropical beach. Cyan is one of the common inks used in four-color printing, along with magenta and black.

In printing, the cyan ink is sometimes known as process cyan, or process blue. While both the additive secondary and the subtractive primary are called cyan, they can be different from one another. Cyan printing ink is more saturated than the RGB secondary cyan, depending on what RGB color space and ink are considered; that is, process cyan is outside the RGB gamut, there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color, pure cyan ink; this is because real-world subtractive color mixing does not produce the same result when mixing identical colors, since the specific frequencies filtered out to produce that color affect how it interacts with other colors. Phthalocyanine blue is one such used pigment. A typical formulation of process cyan is shown in the color box at right. Pure water is nearly colorless. However, it does absorb more red light than blue, giving large volumes of water a bluish tint.

Cyanide derives its name from a blue pigment containing the cyanide ion. Cyanobacteria are an important link in the food chain; the planet Uranus is colored cyan because of the abundance of methane in its atmosphere. Methane absorbs red light and reflects the blue-green light which allows observers to see it as cyan. Natural gas, used by many for home cooking on gas stoves, has a cyan colored flame when burned with a mixture of air. Cyanotype, or blueprint, a monochrome photographic printing process that predates the use of the word cyan as a color, yields a deep cyan-blue colored print based on the Prussian blue pigment. Cinecolor, a bi-pack color process, the photographer would load a standard camera with two films, one orthochromatic, dyed red, a panchromatic strip behind it. Color light would expose the cyan record on the ortho stock, which acted as a filter, exposing only red light to the panchromatic film stock. Cyanosis is an abnormal blueness of the skin a sign of poor oxygen intake. Blue–green distinction in language Shades of cyan List of colors


Śatapāvalī is a Marathi term which refers to an age-long Indian custom of taking a stroll after a meal. The word is a dvigu compound from shata "hundred" and paaul "step", which means "walking 100 steps" after a meal. Experts believe that walking at least 100 steps after eating your dinner improves your overall wellbeing; this includes proper digestion, burning calories, better control of blood sugar levels and triglycerides in the body. Here’s how a 15-minute walk after meals can transform your health and prevent various health complications; the process of digestion is initiated soon. The gastric juices and enzymes responsible for digestion are stimulated in the mean time. However, if a person walks after eating his dinner, the process of gastric emptying of the meal is accelerated leading to better digestion; this is turn, prevents various stomach complications such as acidity or indigestion that people complain after having their meals. Apart from caloric intake and pattern of eating, leading an active physical life is one of the key reasons to boost metabolism.

Hence, people are advised to go for a walk after having their dinner as it stimulates the metabolic process and influences the functioning of other organs in the body. The habit of going to bed after having dinner is not good for health. However, a few minutes of walking in the lawn or in your house can do wonders to your health, it not only improves the blood circulation in the body but relieves stress. This is the reason. A 15-minute walk after eating your dinner not only lowers blood levels of fat but enhances blood circulation to various parts of the body; this is due to the fact that walking ensures proper supply of oxygen and nutrients to the heart which in turn causes better blood circulation. People suffering from type 2 diabetes are benefitted by walking after having their meals. After eating dinner the blood sugar levels spike up due to breakdown of food components, but when you walk after having dinner, the body is physically active which uses the excess glucose present in the blood thereby controlling sugar levels.

Although a 15-minute walk after dinner is a must to lead a healthy life, it plays a key role in weight loss. It is one of the most effective and simple ways to maintain a healthy weight as walking not only burns calories but improves your overall health Colberg SR, Zarrabi L, Bennington L, Nakave A, Thomas Somma C, Swain DP, Sechrist SR. Postprandial walking is better for lowering the glycemic effect of dinner than pre-dinner exercise in type 2 diabetic individuals. J Am Med Dir Assoc. 2009 Jul. Doi:10.1016/j.jamda.2009.03.015.
