Rendering a color wheel
You can fill a selection with a radial blend of colors by choosing
Image > Filter > Render > Wheel. The rendered effect looks like the
color wheel preview in the Hue/Saturation dialog box. The Wheel
filter works with paint objects in RGB Color and CMYK Color.
Unless you make a selection in the image, the Wheel filter replaces
the entire image. If you want to apply a translucent wheel effect, fol-
low the steps for the procedure Applying Clouds filter to selections
on page 35.708, but in the seventh step, choose the Wheel command.
