Chromatic filters can only work if the scene have colors that can be blocked and transmitted by the particular filter.
The well known example: green and red apples. They will look alike in a black & white photo. But a green filter can make the green apples lighter and the red apple darker, so changing the contrast between the two types of apples.
Use chromatic filters carefully! if you want to make the sky dramatic, you may use a red filter. a thunderstorm effect may be achieved, but the trees and leaves may be very dark!
