I still have some ways to go before 60, but starting to feel it already.
I just found this old article on FSM which says the colour was ANA 616 sand which then faded to pink.
This is backed up by a list of US paints on IPMS Stockholm,
www.ipmsstockholm.org/…/stuff_eng_colorcharts_us.htm
It also gives a few paints that can be used to achieve this. How you would then lighten it to the pink hue is another matter.
