MAC Chilled on Ice is a slightly warm-toned, very light gold with a frost finish. It is a discontinued eyeshadow that retails for $23.00 and contains 0.17 oz.
MAC Chilled on Ice Pro Longwear Paint Pot ($18.50 for 0.17 oz.) is described as a "frosted white gold." It's a pale peach with a bright golden shimmer-sheen. At certain angles, it almost looks cool-toned. Shades like Maybelline Barely Branded and Estee Lauder Halo both have a warm, golden kind of coloring, but they don't have the same sheen or base color. Make Up For Ever #101 is the closest dupe I could think of, but it is a powder product, and it is not as metallic.

A highly pigmented, long-wearing, blendable eye primer and/or cream shadow – M·A·C Pro Longwear Paint Pot goes on creamy and dries to an intense, vibrant finish that lasts for 24 hours. The innovative second skin-like creamy shadow formula blends smoothly over lids and creates seamless, buildable coverage without looking heavy or cakey. Its superior colour purity stays true and will not streak or crease. Pro Longwear Paint Pot can be mixed with other products, like M·A·C shadows and liners.
