高齡化社會已是現今不可忽視的現象，如臺灣將於2025年達到20%高齡化人口結構。高齡者的視覺變化會隨著年齡增長產生變化，進而與年輕人產生差異，在日常生活中的色彩設計較少考慮到此一變化，使高齡者可能較難辨識目標色彩，使安全性與便利性都產生限制。然而高齡化色覺議題逐漸被許多國家所重視，在專家、學者們的努力下對高齡者的色覺變化進行研究與分析，並且設計了使不同色覺都能適用的標準。
本論文對於高齡者的視覺變化，採用了三種不同的色覺模型來模擬呈現，以CIE 170-1：2006頒布的色匹配函數為基準，並以Okajima為代表的人眼水晶體光譜透射率模型與Yaguchi為代表的異常三色覺對立色模型作為對照組，探討當不同年齡時可能的色覺變化。再者，針對以上的模擬參數，搭配X-Rite ColorChecker彩色導表上18個有彩度色，經過三種模式之色度轉換後，參考日本工業標準的安全色色度座標範圍，在CIE u’v’均勻色度圖上進行安全色色度模擬，判斷輸入色色度座標是否為安全色，最後以臺科大徽章為例，進行實際色樣本之著色模擬，此概念可作為推廣色彩通用設計的參考。

The aging society is now a phenomenon that cannot be ignored. For example, Taiwan will reach 20% of the aging population in 2025. The visual changes of the elderly will change with age, which will be different from those of young people. The color design in daily life is less considered of this change, which makes it more difficult for the elderly to recognize the target color, and makes the limitation for safety and convenience. However, the issue of aging color vision has begun to be valued by more and more countries. With the efforts of many experts and scholars, the color vision changes of the elderly have been studied and analyzed, and standards that can be applied to different color visions have been designed.
This research uses three different simulation models to present the visual changes of the elderly, based on the standard issued by CIE Color Matching Function (CIE 170-1：2006), Okajima model (Aged human lens model), and Yaguchi model (Anomalous trichromats model) to explore possible color vision changes at different ages. Then, for the above simulation parameters, match the 18 color patches on the X-Rite ColorChecker chart. After chromaticity conversion, refer to guideline of the JIS safety color standard, and generate CIE u’v’ chromaticity values to judge whether the chart’s colors are safety color. Finally, the simulation method was applied to color actual illuminated sample (university badge of Taiwan Tech), which indicates different color appearances at the ages of 20 and 80.
