The limitations of Sexual Selection

A female who prefers the most brightly colored mate in the vicinity isn't going to be subject to adverse selection as a result. And she's always going to pick some mate, therefore her genes are always going to be passed on, assuming she lives long enough.So where this preference is widespread, males will equilibriate at the greatest, boldest coloration they can maintain in the face of predation. Shouldn't they?

I don't see how. Her daughters are going to be unharmed by inheriting the preference - or perhaps benefited by it, if the males they're led to mate with are the strongest and fastest. The males are going to benefit by inheriting traits that females prefer, in addition to the increased strength and speed their fathers must have had to survive predation without camouflage.It's evolutionary benefits for all concerned, seems to me. Female mate preference for bold coloration is fitness-friendly for females; the only pressure against it is the pressure of increased susceptibility to predation in males due to easy-to-spot coloration. And that pressure applies only to males.
