同时对比是一种视觉现象,指的是我们感知两个相邻颜色或值相互影响的方式。颜色不是孤立存在的;它们受到背景的影响,对邻近的颜色产生影响。根据梅里亚姆韦伯斯特词典,同时对比是“颜色在相邻颜色上引起其色调,值和强度相反的趋势,并且相互影响相反。根据同时对比的规律,浅,暗红色将使相邻的黑暗,明亮的黄色看起来更暗,更亮,更绿;反过来,前者会显得更轻,更暗,更蓝。“同时对比也适用于价值,颜色的三个主要特征之一,其他是色调和饱和度。当放置在黑色旁边时白色显得更白,当放置在白色旁边时黑色显得更黑。通过从白色到黑色的值变化范围的相同灰度值线将根据相邻值显得更亮或更暗。 “同时对比”是什么意思?作者:Richard McKinley(2007年7月30日)在艺术家网络上演示了一个例子并进一步解释了同时对比。在19世纪科学家和色彩理论家ME Chevreul撰写的这本关于色彩理论的开创性着作中,了解更多关于“和谐原则”和“色彩对比及其在艺术中的应用”(从亚马逊购买)的同时对比理论,由Faber编辑Birren(转载2007年)。当对立面彼此相邻时,同时对比度尤其强烈,如黑白(相对于不同的灰度值)。因此,彼此相邻的互补色(色轮上相反)也会显得更亮更强烈;例如,绿色在红色旁边显得更加强烈,红色在绿色旁边显得更加强烈;蓝色在橙色旁边显得更加强烈,橙色在蓝色旁边显得更加强烈。汉斯霍夫曼的绘画,Equinox(1958),展示了相邻互补色的关系和强度创造了空间的推拉,因为观众的眼睛专注于颜色的对比。通过接近和饱和来增强同时对比度。相邻颜色彼此越接近,并且它们越强烈,同时对比的效果越大。如果在其中一种颜色周围放置中性色缓冲液,则可以减轻同时对比度的影响。当相邻颜色高度饱和时,同时对比度增强;当相邻颜色较不饱和或较中性时,同时对比度较弱。

Contrast is a visual phenomenon that refers to the way we perceive two adjacent colors or values to interact with each other. Colors do not exist in isolation; they are affected by the background and affect adjacent colors. According to the Merriam Webster Dictionary, at the same time the contrast is “the color causes its hue on the adjacent color, the opposite of the value and intensity, and the opposite effect. According to the law of simultaneous contrast, shallow, dark red will make adjacent Dark, bright yellow looks darker, brighter, greener; in turn, the former will appear lighter, darker, and more blue. “The same contrast applies to value, one of the three main characteristics of color, the other is Hue and saturation. White appears whiter when placed next to black, and black appears darker when placed next to white. The same gray value line that varies by the value from white to black will appear brighter or darker depending on the adjacent value. What does “simultaneous comparison” mean? Author: Richard McKinley (2007, July 30) on the artist demonstrates an example of the network and further explain the simultaneous contrast. In this groundbreaking work on color theory by scientists and color theorist ME Chevreul in the 19th century, learn more about the “harmony principle” and “color contrast and its application in art” (purchased from Amazon) At the same time contrast theory, edited by Faber (Reprinted 2007). When the opposite faces are adjacent to each other, the contrast is particularly strong, such as black and white (relative to different gray values). Therefore, the complementary colors adjacent to each other (opposite to the color wheel) will also appear brighter and more intense; for example, green appears more intensely beside the red, red is more intense next to the green; blue is more intense next to the orange, orange It looks even stronger next to the blue. Hans Hoffman’s painting, Equinox (1958), demonstrates the relationship and intensity of adjacent complementary colors that create space for the push and pull because the viewer’s eyes focus on the contrast of colors. The simultaneous contrast is enhanced by proximity and saturation. The closer the adjacent colors are to each other, and the stronger they are, the more effective the contrast is. If a neutral buffer is placed around one of the colors, the effect of simultaneous contrast can be mitigated. When the adjacent colors are highly saturated, the contrast is enhanced at the same time; when the adjacent colors are less saturated or more neutral, the contrast is weaker at the same time.
