The human eye tends to adjust to local lighting conditions, so an object that looks white in a dimly lit room may in fact be less bright than an object that looks grey in full daylight.

人眼倾向于以适应本地的照明条件，所以，一个物体在昏暗的房间里看起来是白色的，并不比在日光下灰色的物体亮。

The room in which the object was installed was a high white room with a wooden floor - very bare and without any detail.

该物品所在的房间，墙面为白色，地板为木地板——非常空旷，没有任何细节。
