Click the disclosure triangle on the left side of the color controls to expose individual Red,
Green, Blue, and, when applicable, Opacity sliders.
Pop-Up Color Palette
When you control-click a color well or click the adjacent downward arrow, the Motion
pop-up color palette appears. Click in the top area to select a color from the spectrum
of hues, saturation, and lightness. Click in the bottom gradient to select a grayscale value.
As you drag in either area, the pointer becomes an eyedropper, the column on the right
displays the RGB and HLS values for the sampled colors, and two swatches above the
RGB information display the current and sampled colors. As you sample in the spectrum,
the selected object in the Canvas updates dynamically.
The Colors Window
You can also use the Mac OS X Colors window in Motion, giving you access to the familiar
color pickers such as the Web Safe Colors palette or the Crayons palette.
