  1. Mean energy intake scores (± SEM) during the three test days (n = 54). All participants visited the serving table for the 1st round with white, red or black plates (n = 54). Data on the 2nd visits to the serving table consisted of n = 13 participants for white plates, n = 16 participants for red plates, and n = 15 participants for black plates. § indicates the significant effect of plate colour on energy intake from pasta at the first visit to the serving Table (P = 0.025). * indicates the significant effect of plate colour on energy intake from pasta and drink at the first visit to the serving Table (P = 0.03). ‡ indicates the significant effect of plate colour on energy intake from pasta in total (P = 0.028). † indicates the significant effect of plate colour on energy intake from pasta and drink in total (P = 0.021). Post hoc tests did not show a significant difference between red and black plates (P > 0.05)
