Gestalt Theory is a psychological concept concerning human perception of various things as a whole (wholeness) rather than as discrete parts. This theory has been widely applied in design, including logo design, to create appropriate, interesting, and easily memorable recognition, relying on the key principles of Gestalt as follows:

- Proximity
• Arrange related elements close together to be seen as a single group.
• Use spacing between elements to distinguish differences and prioritize.
• Organize elements systematically, avoiding disorder or excessive crowding. - Similarity
• Design elements with similar shapes, sizes, colors, or characteristics to show relationships or group identities.
• Use similarity to create unity and harmony in the logo.
• Create emphasis by using differences or contrasts in color, shape, or size to make certain elements stand out. - Continuity
• Create continuous and fluid lines or movement to guide the eye and produce a natural feel.
• Use the continuity of lines, shapes, or elements to connect different parts of the logo.
• Avoid placing conflicting or opposing elements that may disrupt perception and continuity. - Closure
• Design a logo that appears incomplete but invites viewers to fill in missing parts with their imagination.
• Use lines, shapes, or negative space to create hidden images or meanings.
• Attract attention and stimulate audience engagement through thought-provoking and imaginative designs. - Figure-Ground
• Create balance and contrast between figures (positive) and ground (negative) in the logo.
• Use positive negative space (white space) and negative space (colored background) effectively to convey meaning.
• Design a logo that remains clear in meaning regardless of the background color. - Past Experience
• Consider the past experiences and learning of the target audience that may affect their interpretation of the logo.
• Select familiar and easily understandable symbols, colors, and shapes for the target audience.
• Avoid using elements that may create confusion or misinterpret the intended meaning.
Applying Gestalt principles in logo design will help make the logo interesting, visually appealing, clearly communicative, and easy to remember. By designing a logo, one relies on cohesive element arrangement, the creation of linked hidden meanings, effective use of negative space, alignment with the perception of the target audience, and stimulating thoughtful engagement and imagination. This will lead to creating logos that are appealing, impressive, and memorable for the viewers sustainably.
