Which term would best describe patterns that are recognizable but not realistic?

The term that best describes patterns that are recognizable but not realistic is "stylized pattern." Stylized patterns simplify or exaggerate features of the subject, capturing the essence of an image while departing from actual representations. This approach allows designers to express ideas creatively, making use of color, shape, and form without the constraints of realism.

In contrast, geometric patterns are based on shapes and forms, adhering to the principles of geometry, which may not fit the description of being recognizable in terms of a specific subject. Abstract patterns are representations that do not necessarily depict anything tangible and are often more about color and structure than recognizable forms. Realistic patterns aim for an accurate depiction of a subject, which directly contradicts the idea of being recognizable but not realistic. Thus, "stylized pattern" is the most fitting term in this context.
