3.Color derives from the spectrum of light (distribution of light energy versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. So let’s place a pure blue sphere in the room.
(3.颜色是光谱(与波长相对应的光能)与眼睛里敏感的光线感受器相作用的结果。让我们在房间里放一个纯蓝色的球。)
d.color (颜色)

Does it look natural? NO
(你觉着它看上去自然吗?不)
We have; existence of the light on the floor, object, its shadow and color of course, so why it’s not natural. If it’s not then something is missing.
(在地板上,物体上,他们的影子上都有光,当然还有颜色,这就是为什么它不自然的原因。如果不是这样,那么肯定有些东西丢失了。)
Let’s go and find it!
(让我们继续,并发现它!)
4.To understand it more clearly lets paint the room with all pure bright Green color.
(4.为了更清楚的理解它,让我们给房间一点纯净的绿色。)
Does it look natural? NO
(它看起来自然了吗?不)

We know that some part of light is directly in contact with that ground, it comes back, bounces, just like a ball falling from a height. As the bounce of the ball decreases in the height per contact with the ground so does it’s! [Lights] its intensity is decreased per contact.
(我们知道 一部分光是直接照射到地面上的,他又返回来,反弹,就像一个球从高处落下一样。每接触地面一次,球的反弹高度也随之降低,光也一样。每反弹一次,光的强度也随之而降。)
That’s the bounce of the light and its will be getting bit of green 9as the floor is green, so some green will merge to blue and produce a color somewhere between them.
(下图展示的就是是反弹的光线,它有一点点绿,因为地板是绿色的,所以一些绿色会合并到蓝色上,并混合出介于这两者之间的颜色。)

e.light bounce (so we can see the other side of the object as well with only one light)
(光线反弹(所以即使在只有一盏灯的情况下,我们也能看见物体的另一边。)
[The bounce light will be from the brightest part of the ground, not from the shadow side]
(反弹的光来自地面最亮的部分,而不是来自阴影部分。)
5. We claim to say that this is plastic, metal, rubber! How we say so, nature of the object in terms of visual form, is due to its reflective behavior. Explore this topic it’s got its own dimensions
(5.我们宣称那是塑料,金属,橡胶!我们为什么会这样说,物体的本性体现在了视觉形象上,这是因为他的反射现象。在此不深入探索这个主题。)
