ABSTRACT:
A method for color grading within a component color space associated with a display includes receiving a source image comprising a plurality of pixels, wherein each pixel is associated with a color comprising a plurality of color component values in the component color space, wherein the component color space comprises RGB, and wherein a pixel is associated with a color inside a gamut of the display but outside a gamut of a target media, receiving a color grading signal from a user, modifying the color associated with the pixel from the plurality of pixels in response to the color grading signal, to form a graded image comprising the pixel, wherein the pixel is associated with a graded color comprising a plurality of color component values, displaying the graded image on the display to the user, automatically performing a gamut remapping of the graded color associated with the pixel, to form a gamut remapped image comprising the pixel, wherein the pixel is associated with a gamut remapped color comprising a plurality of color component values, wherein at least one color component value of the graded color is substantially similar to one color component value of the gamut remapped color, and displaying the gamut remapped image on the display to the user, wherein the gamut remapped image comprises a plurality of pixels, wherein each pixel from the plurality of pixels is associated with a color within a gamut of the target media.
