Sir, – The orange colours in your main graph regarding working from home were confusing ("The truth about working from home", News, March 27th). The colours seemed to range from burnt orange to fizzy orange and required microscopic levels of close analysis to differentiate one from the other. What about using other colours such as mellow yellow, deep purple, or the classic black and white? – Yours, etc,
