The generic advice is that increase exposure by "x" stops.

Is there not a better way than this ?

How is this working here, have I got it right, take for example yellow filter if I add a stop I am making yellow and white even brighter when in effect I only want to darken blue. Would the filter not be more effective if I metered off something yellow and then exposed for that without opening up a stop to get maximum effect on the blue sky.
