Using the Adobe Photoshop
Color Picker
You can use the Adobe Photoshop Color Picker
to select the foreground or background color by
choosing from a color spectrum or by defining
colors numerically. In addition, you can select
colors based on the HSB, RGB, Lab, and CMYK
color models and choose from several custom
color systems (see "Color modes and models" on
page 63). By default, the program uses the Adobe
Photoshop Color Picker.
To display the Adobe Photoshop Color Picker:
Do one of the following:
Click the foreground or background color
•
selection box in the toolbox.
Click the active color selection box in the
•
Color palette.
Specifying a color using the color field
and color slider
With the HSB, RGB, and Lab color modes, you
can use the color field and the color slider in the
Color Picker dialog box to select a color. The color
slider displays the range of color levels available
for the selected color component (for example,
R, G, or B). The color field displays the range for
the remaining two components—one on the
horizontal axis, one on the vertical.
For example, if the current color is black and you
click the red component (R) using the RGB color
model, the color slider displays the range of color
for red (0 is at the bottom of the slider and 255 is
at the top). The color field displays the values for
blue along its horizontal axis, for green along its
vertical axis.
To choose a color:
1 Click a component next to the HSB, RGB, or
Lab values.
2 Select a color:
Drag the white triangles along the slider.
•
Click inside the color slider.
•
Click inside the color field.
•
When you click in the color field, a circular marker
indicates the color's position in the field.
