You are totally mistaken, colour definitely helps.
In fact I am fairly certain that accident reports have commented that depiction of terrain on charts should be required (most do but a significant number don't) and that if they are in colour it makes it much easier to quickly interpret the chart.
It may well have been after the tragic loss of the Dan Air 727 at TFN.
I much prefer Aerads, from what I can understand though they contain many inaccuracies and Aerad don't send somebody to your aeroplane to change the charts over.
