I would do a bit of research, figure out a fertilizer regimen for it and see if that doesn’t green it up. Increased light with no increase of nutrients will sometimes cause them to yellow like that. You can get soil tests at most hardware/lawn and garden stores. You might grab one to go with the fertilizer so you can keep an eye on it and don’t burn it.

It almost looks like light shock, how long has it been outside? How often do you fertilize? When was the last time it was repotted? How often do you water, and does the soil dry out between waterings?

Could’ve just tossed his ass in, he’d be invincible, he’d manage…
