Don't get too wrapped up in this issue, certainly don't assume that red times means hard to get. II and RCI use the same basic system. Red means more demand than availability in general, yellow means about the same and green (or blue) means more availability than demand. Still, there is a lot of difference between red for summer in Aruba vs winter (higher) and a lot of difference between HH summer and Orlando summer (both red). I think one can make assumptions about yellow/blue/green but when it comes to red think pink, red and bright red with all types of shades (and thus demand) variations in between.
