Hexadecimal Colors

Hexadecimal colors

A method of color coding RGB for HTML for the web. A complex code based on a 16-unit mathematical combination. HTML uses this six-digit numerical (0-9) and letter code (A-F) to identify specific colors that a designer has chosen; RGB conversion charts to hexadecimal code are readily available.

CMYK, RGB, HSV

These are software color display modes

CMYK mode

This mode of color display imitates the results of mixing process colors. It facilitates working on-screen for print production.

(0%, 0%, 0%,0%)

White in CMYK mode (a total absence of ink on white paper)

RGB mode

This mode of screen display parallels the behavior of light. When 100% each of the three colors is mixed, the result is white.

(255, 255, 255)

White in RGB mode

(0, 0, 0)

Black in RGB Mode

HSV Mode

Stands for Hue, saturation, value or HSL (hue, saturation, lightness) displays a circular color map. Next to the map are three boxes one each for hue, saturation and value. The user first selects a color from the map, then instructs each of the boxes to modify that selection.

Gamut

The range of colors reproduced in a color mode.

Websafe colors

These are an informal standard of 216 colors that are generally considered web safe during the early days of personal computers.

Calibration

This is the setting or correcting of a measuring device or base level, usually by adjusting it to match or conform to a dependably known and unvarying measure.
