Red and Blue violin strings are made with a synthetic core of
identical tension to offer the musician the ease of making a mix and
match set. Infeld Reds are warm and dark; Infeld Blues are the more
brilliant and clearer sounding. These two different tonal
characteristics and equal tensions allow the musician to add warmth
or clarity to their instrument without having to experiment with
multiple brands and tensions.
