The present disclosure provides a computer-implemented method of generating a modified color lookup table (CLUT) based on an original image, a profile connection space (PCS) image, and an adjusted image. The method includes, for each PCS pixel of the PCS image, identifying a subset of CLUT nodes corresponding to the PCS pixel. The method also includes identifying a color shift between an original pixel of the original image and an adjusted pixel of the adjusted image, wherein the original pixel and the adjusted pixel are co-located with the PCS pixel. The identified the color shift is associated with each one of the subset of CLUT nodes. For each CLUT node, a combined color shift is determined based on the color shifts associated with the CLUT node. A modified CLUT can be generated based on the combined color shifts computed for each of the CLUT nodes.
