The whole point of radio backlights is to make the display visible in the
dark. I noticed that there is a trend towards blue LED's, and this is a
very bad idea.

Well, at least it's not a brilliant one. If you want to illuminate
something without using too much valuable battery power, you best do
that with an LED that emits light in a spectral range where the human
eye is most sensitive (in darkness), so you can use one with less output
power. This would be roughly around 550 nm, with a tendency to higher
wavelengths as it gets darker. So in theory, something yellow to
greenish should be ideal, maybe also orange. In fact, Sony portables use
green backlighting.
