"(My ERICA is also RED, but they are all made BLACK now as far as I know) "
"RED is soo 1970's "

Well I remember that red was a pretty popular colour among the choices offered in music shops in small towns in the 50s & 60s - red, red, red, ...

Personally black is far 'too cool', and nobody can see what you are playing red is a danger signal, lets people know you're coming

and anyway, as everybody knows...

RED ONES GO FASTER!
