Didn't see to many of the postcard 4th and 5th series sketches. Did all sketches have color in them?
I think all of the series 4 Mark Alfrey "Dead and Buried" sketches had some color accents. In series 5, I believe Neil Camera did mostly b&w "Wander" sketches, along with some in color, and the Matthew Kirscht "Klepto" sketches all seem to have the klepto arm in pink.
