I'm presuming you're male and don't want a foundation? If so, perhaps you could try a dance / theatre shop. Stage make-up used to be thick dark 'pancake' but it has improved over the years. A light brushing from a good powder can be enough to cover uneven skin tone. The brush used and the 'art' of application may need practice.
If you're looking for a female foundation, Diors Airflash is fab. It's a spray on to give that 'airbrushed' look, and providing you get the right shade, it does exactly what it says on the tin!
