Dear Sharon

I thought it was a problem with my television set and twiddled all the knobs until I ended up with everyone looking yellow. Then I realised that these new series are meant to look as though they’ve been filmed by the light of a 40 watt bulb.

I can never work out what’s going on. Now I know I’m not alone and it’s not my tv or my eyes.
