Painting
To specify a color using numeric values:
Do one of the following:
• In RGB color mode (the mode your monitor
uses), specify component values from 0 to 255
(0 is no light, and 255 is the brightest light).
• In HSB color mode, specify saturation and
brightness as percentages; specify hue as an
angle from 0° to 360° that corresponds to a
location on the color wheel. (See “About the
color wheel” on page 65.)
Using Web-safe colors
The Web-safe colors are the 216 colors used by
browsers on both the Windows and Mac OS
platforms. By working only with these colors, you
ensure that colors in art you prepare for the Web
display accurately on a system set to display 256
colors.
To identify Web-safe colors in the Adobe Color Picker:
• Select Only Web Colors in the lower left corner
of the Color Picker, and then choose any color
in the Color Picker. When this option is
selected, any color you pick is Web-safe.
• Choose a color in the Color Picker. If you
choose a color that isn’t Web-safe, an alert cube
appears next to the color rectangle in the
upper right area of the Color Picker. Click the
alert cube to select the closest Web-safe color. (If
no alert cube appears, the color you chose is
Web-safe.)
Using other color pickers
In addition to the default Adobe Color Picker, you
can select colors by using the built-in color pickers
on your system or a plug-in color picker. These
color pickers appear in the General Preferences
dialog box. For information on installing and
using a plug-in color picker, see the documen-
tation that came with the plug-in.
