固有色就是物体本身的颜色，白色盒子的固有色就是这个盒子的白色，但是由于光源原因和环境色的影响，在物体上会出现环境色，光源色等。比如把白盒子放在红色的布上，打暖光。那么白盒子的反光处就会产生红色倾向的环境色，物体的受光面会受到光源色的影响，在画色彩时，固有色一般出现在中间色部分，面积不会很大。
您所说的黑白灰是色彩三要素（纯度，明度，色相）里面的明度关系，也就是素描里面的黑白灰关系。而固有色则是“色相”范畴的。所以画色彩三要素要统一起来一起把握，并不矛盾啊。

这是根据视觉错觉的原理制作出来的一个海报,整体采用黑白灰加一个绿色的点,整体看来很简单整齐.它主要是利用人的视觉错觉原理,当人们从远处看到这个海报时就产生好奇,当近距离观看就会神奇的发现那些白点一闪一闪,视觉疲劳,给人以视觉错觉感,此时为了满足视觉平横需要寻找一个点停留,保持视觉平横,此时就会将目光集中在那个绿色的点上.

不分左右手：
取4只(3+1),必配成1副,剩下2只
再加2只,成4只(3+1)又配成1副,剩下2只,
再加2只,成4只,必配成第3副.
所以最多取8只可配成3副
2
不分左右手,如果要求3幅手套分别为黑、白、灰
因为手套若干,一直取同一种颜色的话,没完没了.无解.
3
如果分左右手,
因为手套若干,一直取到左(或一直取右）没有边界,所以没有解.

至少每种颜色各5只,这样再摸1只就必有第三副,所以一共需要取出16只
