Soldering yellow and white gold

I have never had to solder yellow and white gold together yet,
but have now got a commission where a monogram in 14 k white
gold should be soldered (probably by sweat soldering technique)
to a plate in 14 k yellow gold. Can anybody help me and tell me,
what solder I should use? White or yellow solder?

Thanks in advance

Kind regards from wintery Denmark - we already had the first
snow, but it is gone and the temp. is about 3 - 8 o C.

Niels- I would suggest yellow gold solder- the flow point is
lower than white gold solders of the same karat content. 14k easy
plumb should work fine. Rick Hamilton
