Let us talk about lights- Day Light and Evening Light. Day light is natural light that enter your home during morning and afternoon. Evening light is what you get during evening. But both have different Quality and different Effects on same color inside your room. If you choose a color for your room, ask yourself, whether that room gets more of a Day Light or Evening Light?
