Cadmium yellow was a favorite for some time.  The taste –  sweet, metallic, creamy.  Just like biting into a marshmallow chick you’d get in your seasonal Easter aisle.  Twist the brush between your lips to get that fine point while adding just enough saliva so as not to diminish the vibrancy needed.  Wonder how the white tastes?  Once you add the fine details of light hitting the subject you’ll experience the taste.  Just watch for the lead content.  Don’t want to end up like some one-eared, post-impressionist, Dutch painter.
