Yellow Silver Solder

Does anyone know if yellow silver solder stays yellow after you
solder with it? If it does not, then why is it yellow to start with?
What makes it yellow and what is it used for?

Susan - As a student I used yellow silver solder to solder brass and
nu-gold - we often used these metals, along with copper because of the
substantially lower cost. The yellow silver solder was certainly more
yellow than the standard silver solder we would otherwise use with
these metals. Sheridan Reed
