To date I've been applying highlights as if I was painting a glistening tooth on a cartoon wolf. You know what I mean, the pure white starburst accompanied by a dinging bell when a wolf in a cartoon (or any big toothed creature) smiles.
Well, I've been shown the way - the secret is this - it's the color of the object, PLUS white, PLUS warm yellow (in my case 'cause my light is warm).
No more glistening teeth for me, but I will miss the ringing of the bell every time I put one on.
I think the highlight on this isn't quite warm enough but it's an improvement.
