white/blue/purple/gold items

How does it work?

I understand more stats = change to color "x"

But how?

+5/+15/+40 from average point for Blue/Purple/Gold, I believe.

Orange is for scrolled equips that haven't yet met Blue.

It's more like +8, +23, +40. Eg. my pants are 24 stats above average and they only turned purple when the last scrolled worked (21 -> 24).

White equips are unscrolled, grey equips are below average (scrolled or unscrolled), orange fits in the gap between average and blue.

Also note that HP/MP count as 1 every 5hp/mp

This sounds more correct, although I'd like to point out that there's no Orange equips that hasn't had a scroll land on it. I believe orange denotes "failed scrolling".

Well, orange means it's at least above average

 Spoiler

If you start low enough, scrolls stay grey.

Thanks guys helpful as always.

This doesn't really relate to your question, but I thought I should note that added new colors in one of the recent patches to KMS.

Among these colors is pink and green. I have no idea which stats these happen at though. But I think Pink happens above Gold.

do you have any pictures of pink and green? thats quite interesting.

Why I said Pink is above Gold.

 Spoiler

I don't have one of green though.

Late, but this is what I had from a while ago, where 1 point signifies 1 point above average (or 10 in the case of HP/MP).

Grey: < 0
White/Orange: 0 - 5
Blue: 6 - 22
Purple: 23 - 39
Gold: 40 +

Gray: Below average
Orange: 1 stat above average (Only when scrolled)
Blue: 6 stats above average
Purple: 22 stats above average
Gold: 41 stats above average
Green: 55 above average (Guesstimate)
Pink: 70 above average (Guesstimate)

 Green glow

59 above average. Not my image.
