The main reason for the change to brown/blue/yellow-green is the fairly common red/green colour blindness. Confusing red and green in the old UK system is not a good thing at all.
One of my work colleagues in my first job was colour blind. If not entirely in shades of grey, it was certainly confused.
He stocked up the resistor drawers on one occasion. The result was almost random, and took some while to sort out!
