Figures Viewing Lake by Peter Fabris and Williams Hamilton

To determine which of the options was not achieved using color in the image, we need to understand the different ways color can be utilized in visual design. In this case, we are given four options: emphasis of the central figure, symmetrical balance, unit, and radial balance.

Color can be a powerful tool for creating visual impact, directing attention, and establishing a sense of balance in an image. Let's consider each option and see how color might be involved:

1. Emphasis of the central figure: Color can be used to draw attention to a specific element by employing contrasting colors, bright or saturated hues, or a different color temperature compared to the rest of the image.

2. Symmetrical balance: With symmetrical balance, the design is divided along a central axis, and both sides mirror each other. Color can be used to achieve symmetrical balance by evenly distributing colors on both sides, either by using the same colors or achieving color harmony.

3. Unit: Unit refers to creating a sense of cohesion and visual unity within a composition. Color can be used to bring different elements together through a consistent color scheme or by repeating certain colors throughout the image.

4. Radial balance: Radial balance is achieved when elements in a design radiate out from a central point. Colors can be used to create radial balance by organizing them in a circular or spiral pattern, with the central figure being the focal point.

From these four options, it becomes clear that "unit" is the one that does not necessarily require color. While color can certainly be used to create a sense of unity within an image, it is not the only method available. Other visual elements such as shape, form, texture, or even composition can also be employed to establish a cohesive visual unit.

Therefore, the correct answer is that color was not used in this image to create "unit."
