Lots of photographers don’t know how to use white balance but it’s something they recommend learning. White balance is used to get colors in your pictures as accurate as you can. In order to work with white balance you need to put your camera on manual. Daylight/sunny mode could be used for this as well. The cloudy setting makes the picture look more warm. The flash of the camera can give it more of a warm look. Every camera adjusts to white balance differently so you need to adjust yours. In order to get a blue or green look you will need to warm up your modes.
