Another conundrum...the little red dress!

Looks like it's going to be one of those days... if the problem of character wasn't existential enough, BBC World informs me that under the guise of research in health, my reluctantly yielded tax dollars are being spent by the scientific fraternity to come to the inescapable conclusion that 'Wearing Red boosts attraction'. What?!!?
Rumour has it - oh I do beg your pardon - empirical research has it, that "Women who don a little red dress before going out with a man may find their date more attentive and generous". It is now apparently a proven fact that : "Men said they would spend more money on a woman pictured in red, compared with the same woman wearing a blue shirt. The researchers say that their study is clear evidence that the colour red makes men feel more amorous - even if this is only on a subconscious level. Their volunteers were told they had $100, shown the picture of their "date", then asked how much of that money they were prepared to spend. On average, wearing red meant a more expensive night out, and in general, a higher rating of attractiveness. Women who don a little red dress before going out with a man may find their date more attentive and generous"
While I do suffer from occasional bouts delusions about my scientific bent of mind, I'm just wondering if the superior thought processes at the University of Rochester considered the fact that a little red dress might encourage generosity more than a blue shirt? Hell, a little any dress usually has the potential to loosen more than just a wallet, yes?
Then of course, there is the little matter of irony: It is the male of the species that is afflicted by colourblindness, is it not?
