From what I've seen via daltonize/XScope/etc iOS 7 is significantly clearer for many apps for the common 2 types of color blindness. Do you have tritanopia or something else?
The weather app isn't in "iOS7" default style and is a little hard to read for normal trichromates. And honestly, if only the weather app is crap, not like there aren't 203948203498 weather apps.
Are any of the other apps hard for you to read? I know I'm constantly checking contrast/colorblind appearance in apps from designers who don't necessarily look at designs with CB people in mind.
Invert colors almost certainly will fix things if all else fails, but I suspect "enhance text legibility" or "increase font size" will do the trick for 99% of apps.
