Adobe Color Picker overview
In the Adobe Color Picker, you choose colors using four color models: HSB, RGB, Lab, and CMYK. Use the Adobe Color Picker to set the
foreground color, background color, and text color. You can also set target colors for different tools, commands, and options.
You can configure the Adobe Color Picker to let you choose only colors that are part of the web-safe palette or choose from specific color
systems. Photoshop Extended users can access an HDR (high dynamic range) picker to choose colors for use in HDR images.
The Color field in the Adobe Color Picker displays color components in HSB color mode, RGB color mode, and Lab color mode. If you know the
numeric value of the color you want, you can enter it into the text fields. You can also use the color slider and the color field to preview a color to
choose. As you adjust the color using the color field and color slider, the numeric values are adjusted accordingly. The color box to the right of the
color slider displays the adjusted color in the top section and the original color in the bottom section. Alerts appear if the color is not a web-safe
color
or is out of gamut for printing (non-printable) .
