Design a sleek and elegant logo featuring a stylized olive branch embodying sophistication and modernity. The chameleon should be created with clean, minimalist lines, smoothly integrating into a palette of earthy tones such as terracotta, olive green, cream, and dark brown. Keep the design simple and refined, avoiding overly complex or cartoonish elements, to ensure the chameleon conveys a sense of elegance rather than playfulness. The logo should evoke adaptability and versatility while maintaining a modern, stylish aesthetic that aligns with a professional and upscale brand identity.
