Colorblind people and low-vision people feel difficulty in distinguishing certain combinations of colors. We analyzed general rules behind this phenomena with much higher detail than before by systematically making a large set of color patches with incremental values of CIE color coordinates using a computer, and by asking colorblind and low-vision collaborators to report confusing ranges of these patches. Based on this knowledge, we developed color designs of meteorological information maps for the Japan Meteorological Agency. By laying real-world test samples in our university campus, we also developed a new color design of tactile paving blocks that satisfies both low-vision peoples' demand for clear visibility and architectural designers' preference for blending with the scenery. In addition, we developed a new design of wheelchair front wheels that facilitate easy crossing over tactile blocks and lighter manipulation on tilted roads.

色盲和低视力的人在区分某些颜色组合时感到困难。我们分析了这种现象背后的一般规则，比以前更详细，系统地使用计算机制作了一个大的颜色补丁，CIE颜色坐标值递增，并要求色盲和低视力合作者报告这些补丁的混淆范围。基于这些知识，我们为日本气象厅开发了气象信息地图的颜色设计。通过在大学校园内铺设真实世界的测试样品，我们还开发了一种新的触觉铺路砖颜色设计，既满足了低视力人群对清晰可见度的需求，又满足了建筑设计师对与风景融合的偏好。此外，我们开发了一种新的轮椅前轮设计，使其在倾斜的道路上更容易通过触觉块和更轻的操作。
