A method of facilitating the display of an image. The method includes, in a display system comprising a display panel having pixels and a backlight having individually addressable colored light emitters configured to provide light to the pixels of the display panel, receiving image data corresponding to an image for display upon the display panel, the pixels each having a color to be displayed, so as to collectively display the image. The method also includes, for each pixel, evaluating whether the corresponding color to be displayed is out-of-gamut to the each pixel, so as to form a set of out-of-gamut pixels. A set of virtual primaries is determined so as to define intensities of light emitted by the colored light emitters of the backlight during display of the image, the virtual primaries determined according to the colors of the set of out-of-gamut pixels.
