Color Universal Design without Restricting Colors and Their Combinations

本文提出了一种新的颜色通用设计方法，不限制使用的颜色和他们的组合使用抖动技术。一个关键的想法是，纯色和接近纯色的较暗和较亮颜色的抖动可以通过正常的色觉看起来像相似的颜色，而它们可以通过色觉缺陷来区分，因为一个是纯色，另一个是深色和浅色的图案。通过实验验证了该方法的有效性。

This paper proposes a new color universal design method without restricting usage of colors and their combinations using dithering technique. A key idea is that a solid color and a dithering of darker and lighter colors to approximate the solid color may look as similar color by normal color vision whereas they could be distinguishable by color vision deficiencies because one is solid and the other is a pattern of dark and light colors. Efficacy of the idea is confirmed through some experiments.
