Colour is a very personal thing

it's totally impersonal, measured in Kelvin's.

Not really.
Kelvins only works for black body sources, that act like a hot object
radiating light.
For lights that are not black bodys, such as LEDs or fluorescant,
it's a hell of a lot less clear, as the spectrum diverges
considerably from a proper black body.

all true but 'white' LEDs still look blue, not white.

Objects can look substantially different under lights of nominally the
same colour temperature and brightness.

get away, really ?
