I'd like to think that most people know that colour doesn't really equate to flavour, and hate to see things like this paraded as a truth (helpful quote from this article in the Morning Advertiser).
"If you’re eating as well, remember that darker beers tend to go better with strong flavours (pies and beef) and lighter beers with more delicate flavours (fish and chicken). For spicy foods and curries, lagers have the carbon dioxide ‘bite’ to cut through the strong flavours."
Incidentally, on the same subject, the Hairy Bikers, Tim Atkin and Meantime Brewing Company food experiment clip is brilliant. Have a look from about 23 min or so if you didn't catch it (currently on iPlayer but not sure for how long.) It showed that automatically equating dark beer to red wine and thus going down the same tired food-matching routes doesn't work, and it is worth trying something different!
Now I'm going to have a nice pale beer from someone like... Victory? Yeah, no danger that will overpower my delicate chicken salad lunch.
