The message
from The Wanderer contains these words:

What is the colour like with white LEDs? Is it extremely harsh and cold?

Tends to be rather bluish, which can be a good thing if you're
displaying glass. I had some in some shelves once shining down onto
glass objects. Looked OK - but choose narrow angle LEDs and have quite a
few.
