Yes you can, that is the best part about this product, but when you go from dark to light i would just recommend change your setting to what you want then pump out a small amount and then use it so it gets all of the darker color out.
Yes you can. Although if your really light colored like me, it still is a little too dark for my complextion but I do love it. I like the consistency as well. feels like a liquid and powder in one. with a slight silky feel.
