An experiment was conducted to investigate the crispening effect on lightness differences. The experiment was divided into two parts using surface and CRT colours including 22 and 24 neutral lightness differences, respectively. Each pair was assessed against three to five neutral backgrounds. The results show that there is a clear crispening effect.
