Godly Scrolled Items

So how exactly does the color ranking go then? I don't fully understand the whole system.:f6:

Orange up to 5, then Blue goes up to about +15 stats, purple to ~40, then yellow. It counts all stats an equip adds, compared to their averages.
Clean equips can pretty much be grey (below average), white (near average), or blue (5+ above average, I think)

Scrolls like 10% overall dex (9 stats) are more likely to hit yellow, I've seen it on as low as 26 dex sauna robes, since they're adding about 15 secondary stats as well.

Highest purple item I have is my Morningstar, 23 w.atk 12 str 3 wdef from average (38 total), and my Leomite might be the lowest - 13 atk 5 str (18 total) from average.
