Best is to be colour neutral from the start. If you do that, it'll save trouble when you're trying to go sub-8.I did 750 solves being color neutral, and I never got very close to my normal average, I gave up for about half a year but now I decided to start again. 750 more solves, and I am about 2.6 seconds away from normal. I have improved quite a bit, but definitely not color neutral yet. I think it would take more like 5000 solves to become fully CN.
