I have a white leather chair would like to paint it. Can it be done?

Hometalk has an excellent video on this. Use their search for detailed info

Real leather has to "breathe" or it ill crack . Pain will make it non-porous, the paint will peel off. Consider a stretchy slip cover.

Painting leather is definitely possible and it can come out quite nicely. Check out what this Hometalker did- https://www.hometalk.com/diy/living-room/furniture/giving-old-world-leather-a-farmhouse-makeover-33540024?r=1

Thanks everyone for your answer to my question.

They make paint for leather - Google it and it works great.
