Effectively, halfway between the dark and light.
Effectively, halfway between the dark and light.
It could also be half-and-half -- for example a diagonal cut. (Then the transition to the actual could wipe the wrong color off to one side.)
Or, a shaded gradient, top to bottom, between the light and dark -- so either way the flicker-to-actual is half as harsh. (This could also work well with a fade/wipe to actual.)
