Juliet is a distinctly greenish-yellow name. It starts a vivid, deep green, dips slightly into pink, and ends a light, flowery yellow.
Romeo, on the other hand, is steeped in blaring red, with undertones of midnight blue.
Blue- and green-coded names typically begin with the letters B, D, J, O, Q, T, and W. A similar dark-blue name would be
