The amount of iron in the rutile (or from the body) determines the degree of blue since its reduction to FeO is a key to the effect. Since rutile is variable in makeup, changes in the iron content will change the blue color. The fact that titanium dioxide additions do not make good blues suggests that the iron-titanium mix is the key to good color.
