Does the artist utilize colors that are “warm” or “cool”, and in which parts of the work?
Is atmospheric perspective—in which cool colors recede, creating a blurred background, and warm, clear colors fill the foreground—used?
Do you notice any visual effects, such as optical color mixing, especially when outdoor art is near neon type light?
Texture: What is the actual texture on the surface of the object? Is it rough or smooth? What is the implied texture? Are patterns created through the use of texture?
