Working with the Adobe Color Picker in Lab mode (Photoshop)
The Adobe Color Picker lets you select a color based on the Lab color model. The L value specifies the luminance of a color. The a value specifies how red or green a color is. The b value specifies how blue or yellow a color is.
To work with the Adobe Color Picker in Lab mode: - Open the Adobe Color Picker.
- In the Lab section of the dialog box, do one of the following:
- Click the L option to display all hues in the color field. A hue is selected by either clicking in the color field or entering values in the A and B text boxes. The color slider displays the selected hue with its maximum luminance at the top and its minimum luminance at the bottom.
- Click the A option and the color slider adjusts whether a hue is red or green. Moving the slider or clicking in the color slider changes the range of colors displayed in the color field. The color field also displays the colors' luminance with maximum luminance at the top decreasing to minimum luminance at the bottom. The B (blue or yellow) color component is represented in the color field with blue on the left and yellow on the right.
- Click the B option and the color slider adjusts whether a hue is yellow or blue. Moving the slider or clicking in the color slider changes the range of colors displayed in the color field. The color field also displays the colors' luminance on the vertical axis with maximum luminance at the top. The A (green or red) color component is represented in the color field with green on the left and red on the right.
- Select a color using a combination of the color slider and the color field or entering numeric values in the L, A, and B text boxes.
