| Outline of Final Research Achievements |
Since no previous research exists on the application of the watercolor illusion effect to improve whiteness perception, the feasibility of applying this effect was investigated, for example, in graphic printing and clothing design.
A stimulus presentation device was used to acquire whiteness perception data, and psychophysical experiments were performed. To verify the effect of the changes in the brightness of two chromatic colors used in designs to improve whiteness perception, chromatic brightness was set at three levels: low, medium, and high. Whiteness evaluation experiments were performed using the two-alternative forced-choice method. The obtained results confirmed that changes in the brightness of a combination of two chromatic colors affected whiteness perception owing to the watercolor illusion effect.

| Academic Significance and Societal Importance of the Research Achievements |
水彩錯視効果を活用した白色知覚の向上には、背景色の明るさと図柄に用いた有彩色2色の組み合わせの輝度値の変化が影響することが確認された。白色知覚を向上させる図柄の決定条件を具体的に導くことができたことは、学術的に意義があると考える。
現在は、持続可能な開発目標（SDGS）が世界的規模で掲げられている。この水彩錯視効果を使った白色知覚向上を生活の中で服飾デザイン等に活用することは、色彩学と被服学の両分野の知見を使ったSDGSへの活動にも繋がり、社会的意義も高いと考える。
