Varied Color
Color plays all sorts of tricks. The color that you see in any object depends on many things. Such as the nature of the light falling on the object and what other colors are near to it. It may even depend on what other colors you have been looking at immediately beforehand（预先）. You can test this last effect by using a piece of strongly colored plastic and staring through it with one eye for a minute or so. Now remove（拿开）the plastic and look at any scene, first with one eye and then the other, comparing the colors you see with each eye.
If the plastic was red, for instance, the eye that was covered by it sees the complementary（补足的）color, which is green, and the scene viewed through this eye appears abnormally（异常）green. Similarly（同理）, orange plastic will give a scene in complementary blue. In effect, your eye is trying to compensate（补偿）for seeing too much of one color by adding some of its complementary color.
色彩能玩出很多种把戏。物体的可见色取决于多种因素。例如，照射到物体上的光线，物体所邻近的颜色，甚至连你刚刚看过的颜色都会起作用。这一点可以这样证明：取一张色彩鲜艳的塑料纸，用一只眼盯着塑料纸看一分钟左右，将塑料纸拿开，再四处张望。先用一只眼看，再换成另一只眼，比较一下两只眼所看见色彩的区别。
如果塑料纸是红色的，被盖住的眼睛看到的就是红色的互补色——绿色，而这只眼睛看到的东西就会显得格外绿。同样道理，透过橘黄色的塑料纸看东西，该东西就会显现其互补色——蓝色。实际上，是你的眼睛在长时间看一种色彩后在尽量补充其互补色。
Next Door Neighbors
The affect that colors have on each other when they are close together can be tested in an experiment for which you will need some good, strongly colored paints—— acrylics（丙烯酸的）will do. You will also need paint brushes, white paper, a pencil and ruler.
First, with pencil and ruler, draw three spaced out squares on one sheet of paper, each with sides of 100 millimeters. In the middle of each square, draw another square of 40-millimeter sides. Carefully paint all three small inner squares a uniform（一致的）pale gray（深灰）. Now paint each of the larger squares a different color, for instance, dark gray, yellow and red (right).
When the paint is dry, study the effect one color has on another. You know that the small squares are all the same shade of gray, because you used the same paint to cover them, yet they no longer look the same. The shade（色度）of gray has been affected by the color next door to it. Of course, this is not a real effect but it is your eyes that are playing tricks on you. More tricks are in store for you if you repeat the experiment, each time using a different color for the small squares. Some great artists know about the next-door-neighbor effect and use it in their paintings.
邻近色
邻近色互相之间的作用可以通过试验来检验。做这个试验需要的材料有丙烯酸颜料这样的硬颜料，还需要画笔、白纸、铅笔和尺子。
首先，用笔和尺子在一张纸上隔开一定距离画出三个边长为100毫米的正方形，在每个正方形的中间，画出边长为40毫米的小正方形。小心翼翼地将里面的小正方形涂成同样的颜色，现在把大的正方形涂成不同的颜色。比如，涂成深灰色，黄色和红色。
当颜料干燥后，仔细观察一种颜色对另一种颜色形成的影响。本来三个小正方形的颜色都是灰色，因为当时用的是一样的颜料。但现在看上去它们的色彩却有所不同。灰色的色度受到邻近色的影响。当然，这不是事实，而是你的眼睛产生了错觉。如果你重复以上的实验，每次都将里面的小正方形涂成不同的颜色，就更能感觉这种错觉的存在。一些伟大的艺术家深知邻近色的效果，并将它运用于绘画实践中。
