Abstract：Colorful paintings were widely used to study the colour quality of museum LED lightings.Several psychophysical experiments were conducted in recent years, to study the colour appearance and the observer preference on paintings under LED lightings with various illuminance levels, colour temperatures, colour fidelity levels, and sizes and shapes of colour gamut.The results were compared with other researchers'' worldwide.The optimal colour temperature for museum lightings was found to be very culture dependent.In Asia, it was found between 3 000 K and 4 000 K.The colour fidelity and the colour gamut of LED lightings have significant effect on the visual perception on painting.It all points toward a spectrum tunable lighting system for illuminating fine art paintings.
