In this paper, we present a computationally-efficient gamut mapping algorithm designed for tone-mapped images, focusing on preserving hue fidelity while providing flexibility to retain either luminance or saturation for visually consistent results. The algorithm operates in both RGB and YUV color spaces, enabling practical implementation in hardware and software for real-time systems. We demonstrate that the proposed method effectively mitigates hue shifts during gamut mapping, offering a computationally viable alternative to more complex methods based on perceptually uniform color spaces.
