SexyCooldown has the great option to custom-color the icon borders based on buff/debuff/cd type. A great addition would be to apply the color of the buff/debuff/cd with the shortest time remaining to the bar (like ForteXorcist does) for a more immediate recognition.

Example: self buffs are set to blue and debuffs to red. On the bar there are two events: one buff (blue) that will expire in 3 seconds and one debuff (red) that will expire in 5 seconds. What I mean is that the bar should be blue, since the buff is the next to expire, then red when the buff is expired and the debuff is 2 seconds away, then finally back to default color when no buffs/debuffs/cds are active.
