Gpuimagefilter like CISpotColor #2262

I'm trying to recreate a custom gpuimagefilter that's like the core image filter "CISpotColor", but I haven't had much luck in replicating the same functionality as CISpotColor. Is there a filter like spot color? Or does anyone have any advice or sample code that reproduces the same result?
