1. What is color?
Color is the aspect of thing that is caused by differing of light.
We can not see color without light. When light sign on an object some color bounce off the object and other are absorbed by its. Human’s eye only see the color that are bounce of the reflect.
2. Additive Color ( Primary Color)
RGB combination show color by adding light. This is call additive color. When RED, GREEN, BLUE are combine together it create the “WHITE” color. It’s look like the white color in a prism.
3. Subtractive Color ( Secondary Color)
CMYK stand for Cyan, Magenta, Yellow, and Black ( The “K” actually Stand for key meaning the key place that aligns the color, but modern printers do use the Black color).
CMYK (Secondary Color) combine together show color by absorbing light. This is called “Subtractive Color”. When Cyan, Magenta, and Yellow are combined it’s create the Black Color.
4. Hue, Saturation, Brightness
a) Hue is a term used in art word to define the family of a color. Any particular spot on the color wheel, from 0 to 360 degree is refer to a hue, which specifies a specific tone of color.
Hue differs slightly from color because a color can have saturation or brightness as well as a hue.
b) Saturation is the intensity of hue from gray tone ( no saturation) Pure color tone. Saturation (or ‘chroma') defines the intensity of a hue. Vivid primary colors are highly saturated, while pastel colors are unsaturated. Monochrome (black and white) prints are totally de-saturated since they lack color intensity.
c) Brightness (Luminance) is related to lightness or darkness of a particular color, from black (no brightness) to white (full brightness).
Brightness (which is sometimes referred to as ‘value' or ‘tone') relates to the amplitude of the colour - or its proximity to the white or black end of the tonal scale. A colour with low value is close to black, while one with high value is close to white.
Photographers use the ‘low' and ‘high' value terms to define the ‘key' of pictures. High-key photographs contain mainly light tones, while low-key images are pitched towards the dark end of the tonal scale.
