Why our grayscale image doesn't look flat
Green looks brighter to us than blue, so a simple average looks wrong. We weigh colors the way the eye does, which keeps skin and skies natural.
Good for print and forms
Some documents must be black and white, and a grayscale file can use less color ink, depending on your printer.
