Titanium is a neutral grey.
It can be described as neutral, medium and colorless.
Set in black, because black reads best on it.
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength that is resistant to corrosion in sea water, aqua regia, and chlorine.
