I use a lot of the same colors, but I really enjoy branching out and using odd colors that I don't see being used a lot. it's entertaining. so I need to expand my commons collection.
plus, I just know that someday there will be an amazing item released in red-orange or something, and then White and I will be the only people with the commons to match with it. XD
I don't even know how much all the items I regularly use of any color are. I started with limited colors and limited items when the site just opened, and I gradually expanded both colors and different items used. I still don't have all the items of any one color, just because I don't like all of them. but I'm sure there's some I want that I just don't know I want yet. XD
