 Because the saturation is not affected by hue, the resulting color mapping may be somewhat dull or muddy; [`luma`](#color-channel-luma) may provide a better result as it extracts perceptual rather than linear brightness, for example `greyscale('#0000ff')` will return the same value as `greyscale('#00ff00')`, though they appear quite different in brightness to the human eye.
