It's hard to say whether blue and red really go together well. It’s a divisive question in the world of color theory. While these two hues aren’t traditional complements (in strict color-wheel terms, blue pairs with orange, and red finds its match in green), their contrast is undeniably powerful.
If you're wondering what color goes with blue, it seems that red may be its lucky companion. "Their relationship is more connected to psychophysiological reactions and cultural associations rather than strict chromatic complementarity," explains color expert Massimo Caiazzo. Red revs up the nervous system, while blue dials it down, creating a dynamic that designers and artists have used to dramatic effect for centuries.
