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) .

When you select a color in the Adobe Color Picker, it simultaneously displays the numeric values for HSB, RGB, Lab, CMYK, and hexadecimal
numbers. This is useful for viewing how the different color models describe a color.
Although Photoshop uses the Adobe Color Picker by default, you can use a different Color Picker than the Adobe Color Picker by setting a
preference. For example, you can use the built-in color picker of your computer’s operating system or a third-party plug-in Color Picker.
Display the Color Picker
In the toolbox, click the foreground or background color selection box.
In the Color panel, click the Set Foreground Color or Set Background Color selection box.
The Color Picker is also available when features let you choose a color. For example, by clicking the color swatch in the options bar for some
tools, or the eyedroppers in some color adjustment dialog boxes.
