The reputation bars you have shown in them pictures are actually horrible, also.. care to elaborate how the current system is outdated?
Nothing in the forum is green except the rep system this disturbs me already ha-ha
The colours have a reason...
Green = positive
Gray = neutral
Red = negative
You can't just change the colours, these colours are clear for everyone.
How about
Purple = postive
Neutral = green
Negative: orange
Brain duck much?:
