Proposed new color ranges

I think that we should change which ranges of hours correspond to red, green and yellow so we encourage people to have a balanced work life. Currently we reward people for working more hours. This will penalize people if they work too much or too little.

Proposed ranges:
0.0 - 3.9 red
4.0 - 4.9 yellow
5.0 - 5.9 green
6.0 - 6.9 yellow
7.0+      red
