Any idea whats amiss.

Is this what you’re trying to generate? Or a LUT already containing specific look?

Hi Vente
I want to create my own custom colours, taken from a laser material test on natural slate. I will photograph the lasered squares which will include all achievable tones from 0% to 100% laser power, and this will be my LUT.

I will then use that table to replace the colours/tones in a photo/image before importing the image to laser software to be engraved on the natural slate or wood.
