Abstract: Image data is received for rendering an image on an image display to a viewer (402). The image data specifies a pixel value of the image for a pixel of the image display to render. The pixel value for the pixel includes multiple component pixel values corresponding to multiple color components of a color space. A color gamut locational value of the pixel value is computed based on two or more component pixel values in the multiple component pixel values of the pixel value specified for the pixel (404). The color gamut locational value is used to determine whether bandwidth broadening is to be applied to image rendering light produced by the pixel of the image display to render the pixel value (406). The image rendering light is directed to the viewer.
