There's something about the changing seasons that makes neglected products feel alluring again. Take, for example, eyeshadow . Those earthy shades that've gone untouched in your palette — like brick red, warm amber, and leathery brown — suddenly feel fresh again. Plus, more practically, the cooler temps mean the pigment (be it a powder or cream ) will actually stick to your lids instead of melting off like they might in mid-July heat.
