About the Change Color window

The Change Color window allows you to create a custom color using one or a combination of the following palettes:

Basic Colors:

Is a palette of basic colors that are preset and cannot be modified.

Color Continuum:

Is a palette composed of all possible hue/saturation combined values.

Intensity/Lightness Scale:

Controls the brightness of the color. It is the only palette available if the chosen color model is Gray.

The color you create using the palettes is visually displayed alongside the color that is being replaced. These are referred to as the New and Old colors, respectively.

The numeric representation of the new color opens in a series of data entry fields. You can edit the entries in these fields and the new color changes accordingly. The number of fields present corresponds to the chosen color model.

RGB:

Is one of the additive color models and is based on the light being emitted from computer monitors. The three primary colors are red, green, and blue. Combining the red, green, and blue colors in various proportions produces all the colors on your screen.

CMYK:

Is one of the subtractive color models and is based on the amount of light being absorbed and reflected by an ink film. This model is often used in printing. The primary colors are cyan, magenta, yellow, and black.

HLS/HIS:

Is a more intuitive model based upon the way we perceive color. The primary components are hue (shade of color), lightness/intensity (brightness of color), and saturation (strength or purity of color).

Gray:

Is a continuum of gray values ranging from pure black to pure white.
