Why does a mirror appear to be silver? When it in fact reflects all light?
gpt
Any perfect mirror will appear silver. Silver in that sense is not a colour but the appearance of a metallic object. So you associate high reflectivity with "silver" even when the mirror is not actually grey. 

White objects are objects which scatter light of all wavelengths, not objects which reflect light of all wavelengths.
