This dialog box is used to manipulate the color of a single color cell in the Image or Plot Colors grids. The color wheel dialog box that appears shows the selected color index number in the window title. The dialog box allows you to modify only the color whose index number is shown in the window frame.

The color wheel uses the HSV color model; i.e., hue, saturation, and value.

Value—Adjust the value, or brightness, of the color from 0 to 100%.

Reset—Re-apply the original color setting to the wheel, but do not exit the dialog box.

Dismiss—Dismiss the dialog box without taking any action.

Help—Display online Help on the dialog box.
