I was being facetious about the clear lens (don't really want to look like a
Japanese tuner car).
But yes, a red lens blocks transmission of all the wavelengths except red.
So the white LED, which is putting out a mixed spectrum of wavelengths (and
thus appears white), is wasting a large proportion of its output on light
which cannot escape the red lens. So is the yellow-white incandescent bulb,
for that matter -- it is just putting out more power to start with.
The red LED is inherently different from, say, a red Christmas light bulb.
The red LED only puts out light in a single wavelength; the "red" light bulb
is a yellow-white glowing filament encased in red glass (or red-painted
glass).
I think you're confused about your sunglasses -- rose-tinted lenses make the
landscape appear, well, rosy.
