Super fires/sulfurs can range from pure white to lots of yellow like yours. With super fires, you see about 15% high white, 15% high yellow and the remaining 70% are anywhere in between. From what I hear, super sulfurs tend to put out more high yellow than the super fires which is cool. For every person that asks me for a high white super I have at least one asking for a high yellow. Either fetch a slightly greater price than the middling yellows.
