I added hair tone to Olga. Each of the ten colors of hair now has 5 tones that are either lighter or darker tones or shades of the original hair color. I also added a seventh hair style that is curly or afro-like style. 

With the new color tones and the new color style there are 840 million ways to change the appearance of Olga. 

Question: Is there enough variation between each of the hair tones of the same color? Should there me more variation?
