Contrast creates emphasis by making a part of a composition visually different from its surroundings, drawing the viewer's attention to that specific area.
Here's a breakdown of how contrast achieves emphasis:
-
Difference and Attention: The fundamental principle is creating a noticeable difference. When something stands out from its background, it naturally attracts the eye. Think of a bright red dot on a gray canvas.
-
Elements of Contrast: Contrast can be achieved through various design elements:
-
Color: Placing a color against its complement is a powerful technique. Warm colors (reds, oranges, yellows) tend to "jump out" against cool colors (blues, greens, purples). For example, a single orange object surrounded by blues will be immediately noticeable.
-
Value (Light and Dark): A strong difference in value, such as a very dark object against a very light background or vice versa, is a highly effective way to create emphasis. This is often used in black and white photography.
-
Shape: An unusual shape can also create contrast. A single circular element among primarily rectangular shapes will draw the eye.
-
Size: Varying the size of elements creates a hierarchy. A larger object will naturally have more emphasis than smaller ones.
-
Texture: Smooth versus rough textures can provide strong contrast.
-
Space: Varying amounts of negative space (empty space) can draw attention to the element that has less space around it. Crowding one area while leaving another sparse creates emphasis.

-
Purpose of Emphasis: Artists and designers use emphasis to:
- Create a Focal Point: Guide the viewer's eye to the most important element(s).
- Establish Hierarchy: Show the relative importance of different elements within the composition.
- Generate Interest: Add visual excitement and prevent monotony.
-
Examples:
- Painting: A single figure in a brightly lit color standing out from a darker background.
- Graphic Design: Using a bold, contrasting color for a call-to-action button on a website.
- Photography: Isolating a subject with shallow depth of field, creating a blurred background and sharp focus on the main subject.
In summary, contrast is a powerful tool for creating emphasis by making certain elements visually distinct from their surroundings, thereby capturing the viewer's attention and guiding their perception of the composition.
