Brands often use specific colors in their logos to convey their brand identity and values. Color psychology plays a significant role in this, with different colors evoking different emotions and associations. For example, red is often used for energy and passion, blue for trust and professionalism, green for growth and nature, yellow for optimism and warmth, and black for sophistication and elegance. Each brand's logo color scheme is designed to stand out and be memorable, helping to build brand recognition.
