MAC By Design is a moderately warm-toned, light-medium copper with a metallic finish. It is a limited edition lipstick that retails for $20.00 and contains 0.1 oz.
By Design Lipstick ($15.00 for 0.10 oz.) is described as a "soft shimmering beige [with a Frost finish]." It's a warm peach with a frosted, m etallic finish. It had semi-opaque color coverage and lasted three hours on me--it was a little drying, too. MAC Posh Tone, MAC Delectable, and MAC Freckletone are all similar in color but lack the metallic finish. See comparison swatches.
