Effects of lighting color on willingness to eat and hedonic impression
of the overall appearance of meal
A two-way ANCOVA revealed no significant interaction between
lighting color and gender in participants’ willingness to eat the meal
[F(2, 104) = 1.42, P = 0.25] nor their hedonic impression of the overall
appearance of meal [F(2, 104) = 0.71, P = 0.50].
As shown in Table 2, color of lighting was found to significantly
influence hedonic impression of the overall appearance of
the meal (P = 0.02), but not in the willingness to eat (P = 0.16).
Hedonic ratings of the overall appearance of the meal were significantly
less under blue lighting (mean ± SD = 5.7 ± 1.7) than yellow
(6.7 ± 1.5; P = 0.006) or white (6.4 ± 1.6; P = 0.049) lighting, respectively.
There was no significant difference between white and yellow
lighting conditions in the hedonic ratings of overall appearance of
the meal (P = 0.46).
There were no significant effects of gender in the ratings of
willingness to eat (P = 0.40) and hedonic impression of overall
appearance of the meal (P = 0.25).
