如何观察表现色彩?长期以来我们习惯于跟着“感觉”走,所谓“画素描靠理性,画色彩靠感觉”,因而常常陷入被动状态,盖“感觉”会随着时间、环境的变化而转变,是不稳定的。例如,我们观察一面灰色的墙,最初的“感觉”是墙倾向于灰紫色,而一旦视神经疲乏,“感觉”就会逐渐迟钝以至混乱(尤其是初学者),墙很可能由灰紫色转向灰蓝色,再由灰蓝色转向灰绿色、灰黄色……如此“感觉”来“感觉”去,终被“感觉”所误。 How to observe the performance of color? For a long time we are accustomed to follow the “feeling” to go, the so-called “draw a sketch by reason, paint color by feeling”, so often fall into a passive state, cover “feeling” will change with time, It is unstable. For example, when we look at a gray wall, the initial “feeling” is that the wall tends to be gray-purple, and once the optic nerve is tired, the “feeling” gradually becomes dull and confusing (especially for beginners) and the wall may turn from gray-purple to gray Blue, and then from gray-blue to gray-green, gray-yellow ... so “feel” to “feel” to go, eventually “feeling” wrong.
