Opinions sought! I'm creating a map of the UK to show annual sales changes by region. The map is roughly divided into counties, then each are is coloured depending on its improvement or reduction in sales - from -30% to +30% I'm trying to decide on the two principle colours to indicate positive and negative results (the colours will be tinted for the other results eg. if -30% is 100% Cyan, then -25% would be 80% Cyans, -20% would be 60% Cyan and so on. My initial thought was to make positive results green and negative results red, but some people in the office think that red is a more "positive" colour Anyone got any thoughts on the most positive and negative colours to use?
