Funny how everybody sees it different. For me negative duv at 4500K looks violet and the light itself as a shade of grey, that’s why I stick to 3000-4000K. But if you like noticeable negative duv a 500K or 1000K difference mix could work out. Tintshots including mixes: [Reference] Nichia E17A/E21A (2000K - 6500K, R9050/R9080, color) CCT and tint shots
