I'm excited! Hair needs more love in TS4! But... I have some complainments:
1. No lighter and darker variants of red hair
2. New blonde swatches looks awesome, but there is no any color variarnt between that light and dark version. It will be good to have something between.
3. Same issue with new black swatches. Colors looks nice, but again I see a huge jump between the shades.
4. No softer variants of color hair. For me existing swatches are too intensive. Toxic green, aggressive pink and another colors which looks like as colors from Paint's palette in late '90.
