Primary and secondary There are two theories about how we can organize the different colours. Physicists explain color as a function of light. This is the Additive model (Mixing lights) White light was first proven to contain all of the colors by the physicist Sir Isaac Newton in the 17th century. Newton passed a ray of white light through a glass prism. By the principle of "refraction“, he had obtained a rainbow pattern (light spectrum) The "light primaries" are different from the "pigment primaries". The light primaries are basically red, green, and blue. The pigment primaries are magenta, cyan, and yellow
CMYK MODEL (Newton´s model) 2. When you want to paint with pigments, you use the Subtractive model, in other words, the CMYK model , CYAN, MAGENTA, YELLOW AND BLACK, the colour that results of mixing all of them.
THE COLOUR WHEEL
PURE COLOUR OR HUE???? The word colour is the general term which applies to the whole subject - red, orange, yellow, green, blue, violet, black and white and all possible combinations Hue is the correct word to use to refer to just the pure spectrum colors. e.g. you can say... Colour: all the hues of the rainbow. Any given colour can be described in terms of its value and hue. VALUE AND HUE?? Value is defined as the relative lightness or darkness of a color. It is an important tool for the designer/artist, in the way that it defines form and creates spatial illusions. Hue also has value. To raise the value of a hue, it is mixed with white. Lowering the value of the hue requires it to be mixed with black
TONE??? What tone means in a painting context is simple. It's how light or dark a color is, rather than what the actual color or hue is. In fact, it`s the same than value. VALUE AND CONTRAST?? Contrast of value separates objects in space, while gradation of value suggests shapes and the outline of a contiguous surface. When you are drawing , value contrast separates the figures from the background. SATURATION?? Saturation: The degree of purity of a hue Value= Hue+Black or White Saturation= Hue+Complementary
Saturated or no saturated?
Complementary colours http://www.worqx.com/color/complements.htm
The complementary color scheme is made of two colors that are opposite each other on the color wheel. This scheme looks best when you put a warm color against a cool color, for example, red versus green-blue. The complementary scheme is intrinsically high-contrast. When placed next to each other, complementary colors make each other appear brighter, more intense. The shadow of an object will also contain its complementary color, for example the shadow of a green apple will contain some red.
