Tilt the glass away from you against a white background and look at the wine where it thins out at the rim. That edge is where colour speaks loudest. Two things matter: the hue (the actual colour) and the intensity (how deep or pale it is).
The 12 colours, pale to deep
Whites: straw to amber
Pale straw and lemon usually mean a young, unoaked white — Sauvignon Blanc, Pinot Grigio, cool-climate Riesling. Gold hints at oak, riper fruit or a few years of age, like an oaked Chardonnay. Amber is either a sweet/fortified wine, a deliberately oxidative style, or an orange (skin-contact) white. White wines gain colour as they age — the opposite of reds.
Rosés: pale pink to copper
Rosé colour comes from how long the juice sat on the red skins. Pale pink is the Provence style — brief skin contact, delicate. Salmon and copper mean more skin time or a touch of age, and usually a slightly fuller wine.
Reds: purple to tawny
Purple edges signal a young red — think Beaujolais or a fresh Syrah. Ruby is the classic mid-life red. As reds age, they lose colour and shift toward garnet, then brick, then tawny at the rim — a reliable sign of a mature bottle. Inky, near-opaque colour points to a thick-skinned grape like Malbec, Petite Sirah or a young Cabernet.
Intensity is a clue too
Pale reds (Pinot Noir, Grenache) tend to be lighter-bodied. Deep, opaque reds usually carry more tannin and structure. None of this is a rule you can bank on every time — but paired with the nose and palate, colour gets you to a confident guess fast.
