...well, I certainly didn't want to start any ill feelings or start a long 
waste of bandwidth on opinions of LED colors. I have said it before and many 
before me have said it as well...

I like purple LEDs myself ;-)

I personally find blue LEDs annoying on several fronts:

a) the beams are *extremely* collomated (sp?). Meaning, they have very narrow angles of
dispersion.

b) my eyes at least are *extremely* sensitive to their wavelength, and like ancient Chubbster,
when I view them "head on" I see spots

c) a friend has a Krell CD player (the one I took the inside photo of) and the power LED is
blueish-white. Man, in a semi-dark room you can read by it. When I was working on it, I covered
it up with duct tape. Same goes for my DVD player: when you place it into double-line-scanning
mode, this horrendous blue-violet LED comes on at 10 candera. Out comes the duct tape.

I like orange ('amber') LEDs as well, and just find the blue LED "unplesant" to look at. However,
this doesn't mean blue LED fans should be banished into a cave and be pitied. I just means you
won't see a 'stock' MOTM with a blue LED :)

So do I.  However, you have to be careful with them because they also 
output quite a bit of UV.  I bought some from www.superbrightleds.com and 
they certainly make things fluoresce well.

Hi,
 I have four blue LEDs on my MOTM-ized Wiard Miniwave. I like the deep color 
blue, but they are a little uncomfortable to look at directly. I installed 
much larger resistors to help dim them, but they are still a little hard to 
look at directly.

  What's strange is that my Sony audio/video receiver has a long / narrow 
blue LED, but it's doesn't give the same "burn a hole in the retina" effect 
as other blue LEDs. This LED is actually quite nice to look at. Kind of 
serene! I wonder if a blue MOTM-style Lumex LED would be any easier on the 
eyes?

 Just to clarify... I know there isn't a blue Lumex LED (not that I've 
found), I was just thinking outloud (only in print).  :)

Some enterprising soul should take apart a bicolor Lumex (has a white 
lens) and try to fit the Lumex shroud/fresnel lens in front of a blue 
LED.

Seriously.
