Light is one of the many waves found on the electromagnetic spectrum. Other waves on the spectrum include ultra violet, radio, microwaves and x-rays. What differentiates light from the others is that it is the only one that can be detected by the human eye. All of the colors we see are a byproduct of spectrum light, as it is reflected off or absorbed into an object. An object that reflects back all of the rays of light will appear white; an object that absorbs all of the rays, black. All of the millions of other colors are produced by a combination of light rays being absorbed and reflected. Grass, for example, absorbs all colors except the ones that make up its color of green.
Primary colors refer to Red, Green(here, green refers to lime) and Blue. They are called that as by mixing varying amounts of these colors any color can be made. Red, Yellow and Blue are often referred to as primaries for a number of reasons, but they really are best for teaching young children about colors and not much more. However, they perform very poorly for actually mixing colors for any practical purpose.
Secondary colors are the colors formed by mixing two of the primary colors .
- Red + Blue = Magenta
- Red + Green = Yellow
- Blue + Green = Lime
A secondary color only consists of the two primary colors it is made up of and contains no traces of the third one. Therefore, the secondary color is said to be a compliment of the primary color. For Example:
Cyan( formed by a mixture blue and green) is a compliment of red. This is called color theory and is a more difficult topic.
Tertiary colors are the colors formed by the mixture of a primary color and its adjacent secondary colors.
- Cyan + Blue = Azure
- Blue + Magenta = Violet
- Magenta + Red = Rose
- Red + Yellow = Orange
- Yellow + Green = Chartreuse
- Green + Cyan = Green Spring
Color phychology is a well-known, yet less explored branch of the study of how our brain perceives what it visualizes. Colors provide the building blocks of our emotions. It is not for nothing that we say we are "feeling blue" or "seeing red". Colors have the power to improve our memory and attention, and even the power to convince us to make a certain decision. Knowing the meaning of colors is key to a better understanding of our behavior.
Colors act upon the body as well as the mind.
Red has been shown to stimulate the senses and raise the blood pressure, while blue has the opposite effect and calms the mind. Yellow, orange and red are associated with the heat of sun and fire; blue, green and violet with the coolness of leaves, sea and the sky. A certain color can evoke a reaction in one person and can often evoke the opposite reaction in another person, due to culture, prior association, or even just personal preferences.
HSL stands for Hue Saturation and Lightness. it is used to specify the hue of the color, which determines what the color will be entirely, Hue is the
biggest factor in making colors. Saturation specifies how intense the color is, how much it stands out from other colors. And finally, Lightness
specifies how bright the color is, too light can make the color white and too dark can make the color black, so we should keep the lightness at a middle level.
In mathematics and computing, the hexadecimal (also base 16 or hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16.
Unlike the common way of representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values 10 to 15.
An example of hexadecimal code would be #00FF00, #0000FF and so on.
We can also shorten the code for primary to tertiary colors, like #0FF and #F00.
People who work with color (artists, architects, interior decorators) do not just use color randomly, they use color wheels and color theory to help create a piece that conveys meaning and emotion. Color has a powerful way of creating "mood," especially when used in a cool, warm, or a monochromatic color scheme. Why do people have a favourite color? It is because they are drawn towards the qualities of the color. Color and color theory is a vast subject and this is only the introduction. There is still a lot to learn about different types of color, color picking techniques, the color wheel and how color affects our life.
