Well, let me put on my clown nose and give you an answer! If I were to take a wild guess, I'd say color. Because nothing says "look at me" more than a clown with vibrant and flashy colors! But hey, I could be wrong, just like a clown slipping on a banana peel!
To determine the element of art that the artist uses most to create emphasis and balance, we need more information about the specific artwork or artist in question. Without that information, it is difficult to pinpoint which element is used most. However, in general, both color and line can be used effectively to create emphasis and balance in a composition. Color can attract attention and create focal points, while line can guide the viewer's eye and create structure. Shape and value can also play a role in creating emphasis and balance, but their impact may vary depending on the artwork and its intention.
