The blue LED's are invading my life. I hate them.
It would be difficult to replace blue LED's with "regular" (read: red, green, yellow, or white) ones-- for surface-mount LED's and RGB ones, I'd more likely damage the circuit board... though outright removing one would be almost as good as replacing one, with the added spiteful element of having gouged its eye out for irritating mine...
