As it is now, the feature was implemented as a stop-gap to tide over users until I could get around to actually standardising all the included weathers' tinting, though it's still fairly bad at that. I'm going to change it from being customisable per-weather-mod to per-weather-type, as that's now where most distinction lies. The RGB settings will remain the same, but they will be customisable differently for each of the 7 weather types (not including Oblivion Gate weather). In addition, rather than affecting the whole gamut of colours, only the sunlight (and possibly ambient too) colours will be affected, though the effected times will be extended from the current day only to the four available sunrise, day, sunset and night times. This should give greater consistence and control over the current system.
I'm also planning on doing a renaming of most of the optional features to make their names, etc. a bit more expressive of their purpose, as the Enhanced * labels work OK for EW, where it fits a pre-existing naming scheme, but in AN we can afford to be a bit more expressive in our nomenclature.
All this is planned for inclusion in the Fix Pack, which I hope to have released before the weekend is over. Then again, unless I get some more reports in on how the fix I posted works, that may not happen. (hint: download and give feedback, people!)
EDIT: @ andalaybay: I'm suspicious of gardening.esp, as I've used the majority of the other mods in your LO at one point or another, and don't remember such a problem. Are you using any sound replacers/additions besides OSSO? Try disabling gardening.esp, perhaps there's a watering plants script running or something that plays the sound of water running, and it's got stuck. :shrug:
