What are the common mistakes when style flat colors 3D models?

Common mistakes when styling flat-color 3D models include using too many colors (cluttering the minimal look), neglecting contrast (hiding key details), and skipping subtle, consistent lighting (losing shape definition). Using too many colors breaks flat style’s core—stick to a 2–3 palette to keep it clean. Neglecting contrast means important edges blend; test in grayscale to ensure clarity. Skipping subtle lighting: even flat looks need soft shadows (like ambient occlusion) to show depth—without it, models appear shapeless, not intentionally flat. For beginners, start with a tight palette, check contrast in grayscale, and add simple occlusion—small steps that avoid pitfalls without overcomplicating.
