PRINT VS MULTIMEDIAPRINT VS MULTIMEDIA

Main Difference• Print

– Primary Colors• CMYK • Cyan, Magenta,

Yellow, Black - Subtractive Color system

– Add together = black

• Multimedia– Primary Colors

• RGB• Red, Green, Blue

– Additive Color system

– Add together = white

CYMK• Subtractive Color

Color system in which cyan, magenta, and yellow are subtracted from white to produce other colors.

• MagentaReddish - purple color which reflects blue and red while absorbing green.

• CyanA greenish - blue color, absorbing red light and reflecting green and blue light.

• YellowA subtractive color which reflects green and red while absorbing blue.

Additive Color System

• Refers to the combination in varying proportions of red, green, and blue light to create the colors of the palette.

• See font selection in PPT for example. (more colors – custom)

Summary• Warning:

Mixing colors in HTML is directly opposite from mixing colors with paint. Low amounts of color make dark shade; high amounts of color make bright shades. With HTML, you are mixing light, not paint.

More infoThere is a fundamental difference between color

and pigment. Color represents energy radiated by a luminous

object such as a cathode ray tube (CRT) or a light-emitting diode (LED).

Primary colors : red (R), green (G), and blue (B). When you see a red area on a CRT, it looks red

because it radiates a large amount of light in the red portion of the electromagnetic radiation spectrum (around 750 nanometers), and much less at other wavelength.

More infoPigments, as opposed to colors, represent energy

that is not absorbed by a substance such as ink or paint.

The primary pigments are cyan (C), magenta (M), and yellow (Y). Sometimes black (K) is also considered a primary pigment, although black can be obtained by combining pure cyan, magenta, and yellow in equal and large amounts.

When you see yellow ink on a page, it looks yellow because it absorbs most energy at all visible wavelengths except in the yellow portion of the spectrum (around 600 nanometers), where most of the energy is reflected.
