You can use:

to determine how many chips you'll need for color-up, etc. You're a little low on greens and blacks for standard colors. As Matthew suggested, 25s will be your workhorse chips for a T1000, so you'll need more of them than anything else. Purples and blues are both out of stock at most places these days, so either hang onto 'em (if you really like them) or trade some for other colors (and at 1.5:1 or so).
Actually, your whites, blues and reds would make a nice ~500 chip $0.25/0.50 NLHE cash set (with whites as $0.25, blues as $1, and reds as $5).
