Subject: Re: changing display color?

Nah, one simply reduces the number of LEDs accordingly and and/or uses the
newer low voltage blue/white available from several sources.
You can pull lots of tricks without changing the circuit.

I've seen how they are mounted though, and it would be tedious indeed to
directly replace them.
