(Image>Adjust>Desaturate)
(Image>Adjust>Replace Color)
Desaturate- This menu command eliminates all color in the image, reducing everything to Black and White. No controls in this one, just select the command and stand back.
Replace
Color- A relative of Hue/Saturation, Replace Color lets you define a
color range within an image and modify or replace it. It shows you a thumbnail
of the image, allowing you to select portions of it with an eyedropper.
A slider adjusts the range of selection, which is updated in the thumbnail
image. Once selected, the standard Hue/Saturation tools let you shift Hue,
Saturation, or Lightness. This is a good control that lets you select an
area by color, and then apply either a radical color shift or a subtle change
in intensity.
