Colour psychology investigates how different colours elicit distinct emotions, perceptions, and connections, hence affecting user behaviour and brand perception in web design. Designers may elicit desirable responses and increase user engagement by intentionally picking colours that are consistent with the intended message, target audience preferences, and brand image. Blue, for example, expresses trust and professionalism, making it appropriate for business websites, yet red captures attention and urges action, making it popular for call-to-action buttons. Understanding colour psychology allows designers to develop visually appealing and compelling
web design for solar companies that reach people on a subconscious level.
