Although a white surface is a strong cue in the judgement of the color appearance of surfaces, the area of a perceptually white surface under different light sources has not been precisely specified. In this study, the Munsell chips categorized as being in the perceptually white area were determined under two different fluorescent lamps with correlated color temperatures of 3000 and 6700 K under three different environmental conditions: an achromatic room, a Japanese style living room, and a modern style living room. The color appearance of the chips surrounding the perceptually white area was also investigated. For all three environmental conditions, the center of the perceptually white area was around the N and 10PB chips with the 6700 K lamp and around the 3PB and 5B chips with the 3000 K one. The number of chips categorized as blue was higher with the 6700 K lamp, whereas that categorized as pink or skin tone was higher with the 3000 K lamp. Comparison of results with the 6700 K lamp with the results using the CIE whiteness equation showed that some of the Munsell chips categorized as white in this study were outside the white area defined by the equation.
