Change background according to weather

The background color of the application according to the weather and temperature.
For example,
Rainy Weather : Blue Color Background

if temperature is greater than 35 degrees, then background changes to red

No file or test is named. Start at the application's entry point and locate where weather and temperature data are displayed; then determine how the background is selected. Done means the background visibly changes for rainy weather and for temperatures above 35 degrees, with the expected colors verified in the running application.
