Well, there are several elements in art including: space, texture, color, form, shape, and of course tone. Lets use space. Space is what gives your photo depth. All pictures should have a foreground, middleground and background. You can use space in your photography by having negative and positive space, allowing the viewer to move their eyes all around the photo.
Hope that Helps!
You can create brown from the primary colors red, yellow, and blue. Since red and yellow make orange, you can also make brown by mixing blue and orange. The RGB model used for creating color on screens like the television or a computer uses red and green to make brown.
