Boundary of acceptable blue color in Thai traffic sign for elderly
Recently, blue traffic sign was officially introduced as a mandatory sign in Thailand where the elderly population increasing. Since the elderly have difficulty seeing blue color, we investigated the elderly vision on blue color in traffic sign. This research aimed to locate the region of blue color which is suitable for the young and the elderly. The subjects were divided into two groups: a group of young subjects aged between 18-23 years old, and a group of young subjects wearing a cataract experiencing goggle to simulate the elderly vision. Ten mandatory signs were used in this experiment. The background color of these mandatory signs was modified from the original blue color and varied to other 51 colors around this point. In each judgement, one mandatory sign was randomly selected from the set of 18 mandatory signs. The background color of the selected sign was filled with a color which was randomly selected from 52 colors. For the first task, subject was asked to judge whether the stimuli was a blue mandatory sign or not. And the second task, subject was asked to categorize the background color based on eleven basic color terms. Our results exhibited that the boundary of the acceptable blue color in mandatory sign for the elderly was larger than the boundary of the acceptable blue color for the young.
