A color model is an abstract mathematical model describing the way colors can be represented as tuples of numbers, typically as three or four values or color components. When this model is associated with a precise description of how the components are to be interpreted (viewing conditions, etc.), the resulting set of colors is called color space. This section describes ways in which human color vision can be modeled.
One can picture this space as a region in three-dimensional Euclidean space if one identifies the x, y, and z axes with the stimuli for the long-wavelength (L), medium-wavelength (M), and short-wavelength (S) light receptors. The origin, (S,M,L) = (0,0,0), corresponds to black. White has no definite position in this diagram; rather it is defined according to the color temperature or white balance as desired or as available from ambient lighting. The human color space is a horse-shoe-shaped cone such as shown here (see also CIE chromaticity diagram below), extending from the origin to, in principle, infinity. In practice, the human color receptors will be saturated or even be damaged at extremely high light intensities, but such behavior is not part of the CIE color space and neither is the changing color perception at low light levels (see: Kruithof curve).
Primary Colors may refer to:
RYB (an abbreviation of red–yellow–blue) is a historical set of colors used in subtractive color mixing, and is one commonly used set of primary colors. It is primarily used in art and design education, particularly painting.
RYB predates modern scientific color theory, which has determined that magenta, yellow, and cyan are the best set of three colorants to combine, for the widest range of high-chroma colors. Red can be produced by mixing magenta and yellow, blue can be produced by mixing cyan and magenta, and green can be produced by mixing yellow and cyan. In the RYB model, red takes the place of magenta, and blue takes the place of cyan.
While reproducing the entire range of human color vision with three primaries in either an additive or subtractive fashion is not possible, RYB achieves a smaller gamut than CMY.
RYB (red–yellow–blue) make up the primary color triad in a standard artist's color wheel. The secondary colors purple–orange–green (sometimes called violet–orange–green) make up another triad. Triads are formed by 3 equidistant colors on a particular color wheel. Other common color wheels represent the light model (RGB) and the print model (CMYK).

The Color Wheel Chart https://colorwheelchart.wordpress.com/ Color Mixing Wheel has 12 colors on it. Primary Colors, Secondary Colors and Tertiary Colors. Primary Colors also called the RYB colors are Red Yellow and Blue and for artists and painting. The RYB colors predates todays color theory. The argument in todays color theory is that yellow, cyan, and magenta are the best three primary colors. There is another color wheel called RGB the colors are Red Green and Blue and used for technology.

I coloured this SVG drawing of an owl I picked up at http://vintagegraphics.ohsonifty.com/royalty-free-stock-retro-owl-vector/ as a means of studying the color wheel and colour theory and also as a handy way of storing color palettes for future work. I focused on triad harmonies of primary, secondary and tertiary colours across RGB, RYB & CMYK models and analogous harmonies of the RGB model. I intend to cover over color harmonies and using tones & shades in further studies.

A brief introduction to CMY colour mixing. Explains the basics of tristimulus theory of colour perception in terms of subtractive primaries and secondaries as used in the printing industry. In explaining the basics of mixing colour pigments, the video focuses on how the pigments absorb or reflect light.
This video is a brief overview of the RYB Framework, as described in the free eBook "Fundraising in Primary Colors: The RYB Framework to Nonprofit Sustainaibility", available at ankhacia.com/ryb-ebook-opt-in.
Primary colors (or primary colours) are sets of colors that can be combined to make a useful range of colors. For human applications, three primary colors are usually used, since human color vision is trichromatic. For additive combination of colors, as in overlapping projected lights or in CRT displays, the primary colors normally used are red, green, and blue. For subtractive combination of colors, as in mixing of pigments or dyes, such as in printing, the primaries normally used are cyan, magenta, and yellow, though the set of red, yellow, blue is popular among artists. See RGB color model, CMYK color model, and RYB color model for more on these popular sets of primary colors. This video is targeted to blind users.

Brown is a composite color which can be produced by combining red, yellow and black, or by a combination of orange and black—as can be seen in the color box at right. The color brown shown at right has a hue code of 30, signifying that is a shade of orange. In the RGB color model used to create all the colors on computer and television screens, brown is made by combining red and green light at different intensities. Brown color names are often not very precise, and some shades, such as beige, can refer to a wide variety of colors, including shades of yellow or red. Browns are usually described as light or dark, reddish, yellowish, or gray-brown. There are no standardized names for shades of brown; the same shade may have different names on different color lists, and sometimes the one name ...

Colors affect us in countless ways—mentally and physically, consciously and subconsciously. Psychologists have suggested that color impression can account for 60% of the acceptance or rejection of a product or service. Good color choices should never be neglected in web design. A bad color combination can have the same negative effect as poor copy and slow load times. 1. http://www.youtube.com/watch?v=CcpZLM951rk 2. affect us in countléss ways—mental| y and physically, consciously and subconsciously 3.
