You sure like to contradict Capital J, don't you? He didn't say Ni
was yellow, he said it was yellower than chrome. And he's right.
Silver is definitely white. Aluminum and tin are sort of white.
Nickel is gray, and it's got a yellower cast to it than most gray
metals, e.g. chrome, stainless, cobalt, tungsten, etc. Kind of like
titanium that way.
US "nickel" currency is only 25% nickel, but it is about the same
color as hard nickel plating. It's paler than the commercially pure
nickel I have worked.
There are a bunch of photos of nickel here, most of which show the
yellowish cast that JB and I are talking about:

Most of the following photos show the not-yellowish color of chrome.
It's not paler than nickel, to my eyes anyway. Just more of a bluish-
gray rather than yellowish-gray.
