Hi,
The red/blue convention is probably based on political view point. The
Capitalists view the red colour and what it symbolizes as negative, which
obviously makes the blue positive. Does that mean we crystallographers are
Capitalists or should each one of us decide on it according to his views ?
Cheers,
Boaz
