Just pay attention to the color temperature and CRI of the new LEDs that
you put in. Cree CR6 is one choice with a high CRI and a low color temp
(former is indisputably good; latter is a matter of preference. But I
cannot see anyone wanting a light much over 4500K anywhere in a
residence... above that is getting into "HID headlamp" territory.)

As my eyes age, I am more and more accepting of the bluish hues of LEDs
because older eyes skew way toward the yellow because of aging tissue:

The conjunctiva turns thinner and more fragile with age and takes on a
yellowish tinge from an increase in elastic fibers. The sclera also assumes
a yellow hue from a collection of lipid, or fat, deposits.

So the bluish-tinged light from some LEDs neutralizes the yellow overcast
that effects aging eyes. I've switched from tungsten filament flashlights
to LEDs because I find it very hard to see as clearly with the old-style
yellowish bulbs. The only exception is the big hand-held 12V spots.
