For example, as shown in FIG. 2, even if the characters 1b to 3b are of the same color, if the background colors are different like 1a to 3a, the colors of the characters 1b to 3b will appear different.
このようにある文字や図形の色や明るさが1周囲の背景
の色や明るさによって変化して見える現象を色対比とい
い、その変化の度合いを対比効果という。色対比は次の
ような特徴を持つ。The phenomenon in which the color and brightness of a certain character or figure appear to change depending on the color and brightness of the surrounding background is called color contrast, and the degree of this change is called contrast effect. Color contrast has the following characteristics.
■0文字や図形の色は、色については、色相環上におい
て背景色と離れる方向に見える。明るさについては、背
景色よる明るいものはより明るく、暗いものはより暗く
見える。鮮やかさについては、背景色より彩度が高いも
のはより高く、低いものはより低く見える。■0 The colors of characters and figures appear to move away from the background color on the color wheel. Regarding brightness, bright objects appear brighter and dark objects appear darker depending on the background color. Regarding vividness, colors with higher saturation than the background color appear higher, and colors with lower saturation appear lower.
■0文字や図形が小さいときほど対比効果は大きい。■0 The smaller the character or figure, the greater the contrast effect.
[3]、背景色の領域が大きいほど対比効果は大きい。[3] The larger the area of the background color, the greater the contrast effect.
[4]、背景色の領域と文字や図形の領域が接している
ほど対比効果が大きい。[4] The more the background color area and the character or figure area are in contact, the greater the contrast effect.
■1文字や図形と背景色の明るさの対比が小さいほど色
の対比効果が大きい。■The smaller the contrast between the brightness of a single character or figure and the background color, the greater the color contrast effect.
[6]、明るさが等しければ背景色の彩度を上げると対
比効果も大きくなる。[6] If the brightness is the same, increasing the saturation of the background color will also increase the contrast effect.
[7]、補色同士の場合、色相は変化せず、彩度が上が
ったように見える。[7] When complementary colors are used, the hue does not change and the saturation appears to have increased.
