What just happened?

White light can be rather flat when it interacts with props and other scene objects, even for a daytime outdoor scene. We wanted to add a touch of warmth to the scene and that can be done by adding a warm color to a light. You'll notice that we didn't change the white color of Light 1 because that will cast a heavy shade of the selected color over everything in the scene. We just want highlights of a warm color. For this we will use Directional/Spotlight 2.

If you don't think this light is affecting the scene then turn it off to notice the difference. Experiment with the orange color to achieve the lighting you desire. Watch out how the orange lighting interacts with the leaves on the tree and also with the other objects. As you adjust the intensity of the orange color, you will notice that moving the slider to a darker color of orange adds more color and less light to the scene.

We will not be changing the direction of the lighting, which is done by selecting the light and using the Rotate tool. Check the light's Show checkbox in the Scene Manager and you will see a colored line on the screen that displays the direction of the light to help in adjusting the light's affect.
