Xrays and gems

By now it’s common knowledge that xrays can change the colour of
gemstones when least desired. But what if you have a citrine with an
unappetizing shade of muddy amber? Can the old Xray machine be of
some use to me here? If there is anything in the archives that could
elucidate this subject, please direct me. (The stone in question is
inclusion free just a shade that doesn’t excite me. I’d prefer a
nearly colourless yellow) Thanks in advance, Judy
