Change a color definition

  1. Place the caret at a highlighted color definition.

  2. Press Alt+Enter and select Pick color from palette from the action list.

  3. In the Choose Color dialog, you can choose colors using three models: AHSB, Web, and ARGB. If you know the numeric value of the color you want, you can enter it into the appropriate text field. You can use the color slider and the color field to choose a color. As you adjust the color using the color field and color slider, the numeric values are adjusted accordingly. When you select a color in the color box, it simultaneously displays the numeric values for AHSB and ARGB, and hexadecimal numbers.
