Exploring an efficient research method for understanding color preference is important to researchers and designers. This work compares four experimental methods for individual color preference research (N-alternative forced choice, rank-order, rating and paired comparison). Three psychophysical experiments were carried out with 338 participants. Participants were presented with six color patches (red, orange, yellow, green, blue and purple) arranged in a random order. This work suggested orange is the strongest preferred color and green is the weakest preferred using three individual color preference experimental methods with six hues. The Monte Carlo Analysis method further compares the result performance for four methods, which suggests the rating, paired comparison and rank-order methods are more stable than the N-alternative forced choice method when only a small number of participants take part in the experiment. For studies involving small numbers of participants (even less than 6), the rating, rank-order and pair comparison methods should be preferred.color preferences, experimental method, Monte Carlo analysis, research strategy
| INTRODUCTIONColor preference per se has been studied by many researchers. 1 It is concerned with which colors individual prefer among alternatives. 2 Individual color preferences vary from person to person. 3 Thus, finding an efficient way to understand individual color preference is important to both researchers 4 and designers. 5,6 The previous studies have used standardised colors, multiple research strategies, and sophisticated statistical methods. 7 From the previous studies, a color preference research strategy includes experimental material, experimental method and experimental environment. 7 The experimental
