“I love colour… but I’m scared I’ll mess it up.”

Sound familiar? You’re not alone. Many of us want a joyful, personal space — but get stuck in fear. What if it clashes? What if it’s “too much”? What if I regret it? That’s not a design flaw — it’s just that no one ever taught you how to design from the inside out.
