For color harmony I treat each fixture like a brushstroke—pick a neutral white or a soft cool tone, then balance it with a warm reflector or a diffused panel so the whole scene stays even. I keep the array minimal; too many colors create chaos, so I stick to one or two temperature ranges and adjust the intensity. Symmetry is key, so I place panels in a grid and tweak spacing until the light feels like a single, balanced canvas. If one panel feels off, I swap it out or add a small LED strip to correct the color cast. Remember, the goal is a clean, unified look—no flashy colors unless the subject demands it.
