Which option would help a user in Adobe Express to create visually consistent branding?

Utilizing a custom style guide is essential for creating visually consistent branding in Adobe Express. A style guide outlines specific elements such as color schemes, typography, logo usage, and imagery styles that are aligned with a brand's identity. By adhering to this guide, users can maintain consistency across various materials, ensuring that all designs reflect the same visual language and reinforce brand recognition. This consistency is crucial for building trust with an audience and effectively communicating the brand's message.

Other options do not contribute to maintaining consistent branding. Turning off templates could lead to a lack of structure in designs, making it difficult to ensure visual uniformity. Randomizing design choices would likely result in a disjointed brand experience, as different elements may clash rather than complement each other. Limiting color use could restrict brand expression rather than promoting it, as many brands thrive on a vibrant palette that is cohesively applied according to a style guide.
