And then find the brightest sunniest spot you can for your cactus. It will not be an immediate color change - I would think 1 or 2 months minimum.

I'll just move it over, as its under a plant light but also gets window sunlight.
Funny how many of the colored grafted cacti are said to die if not grafted, however according to the article and my cactus that can't be fully true, at least for yellow. They just grow REALLY slow!
And, it said plants in the shade that aren't green change green to make up for lack of chlorophyll, I bet this before me was kept dark, hence why suddenly in bright light it lost the green! But that means the myth of colored cacti dying from no chylorophyll is a lie!
