Guild Wars 2

Ok, so im looking at the stuff i can craft, and i notice that as my level in armorsmithing went up, some colors changed in my recipes? Anyone know what that means?

When they change to grey, you get no xp for creating them.

Each color change indicates a lower crafting XP gain for each item crafted. I believe it’s orange, yellow, green, blue, white, gray. Orange is the max cxp and gray is zero cxp.
