AeroWeather is a fun application that sits in the background and retrieves the temperature or current weather conditions for your location, and then set the Windows Vista and 7 Aero color based on the temperature. Now before you proceed to the download page, let me tell you that the application only accepts US zip codes, so it’s pretty much useless for non-US based users.
Once you have launched the application, punch in the zip code of your location, choose the regulator of the color type (temperature or weather condition) and the color range (from zero to 100). The temperature based color ranges between red and purple. When the temperature gets colder, the window color gets closer to purple and during hot seasons the window color shifts towards the reddish hue. If the color regulator is set on condition, the aero color takes a greyish look on cloudy days, blue if it’s sunny, white if it’s snowing, dark grey if it’s raining, etc
Once you get familiar with the window color and the associated temperature and condition, you can gauge the outside condition by just glancing at the window border.
Besides changing color based on weather, AeroWeather has a night mode option that dims the aero colors automatically at night. The colors become less vibrant. The information on the time of sun set is retrieved from the weather server, based on your location.
AeroWeather is a neat utility but has some issues. The lack of support for location outside the US is a bugging one. AeroWeather will also not revert the window color to the initial configuration once you exit the program
