I am not aware of any chemical or physical method for lightening stone unless it has been color enhanced.  I would advise your customer that it can't be done

I have a customer with a dark travertine they want lightened.

I know there are some dyes but they are blue, black, green, gold, blue, etc.

Anyone know if there is a white or biege out there somewhere?

I can wash out some color by honing, but not sure if they want that.
