正如一些人是先天性色盲或者脑部受损后失去颜色知觉，世界上也存在另一些人患有“数字盲”：即无法理解那些平常人觉得毫不费力的事物。

Just as some people are born colour-blind, or lose colour vision after a brain injury, others are "number-blind" : unable to comprehend what everyone else sees effortlessly.

大体意思就是说几个孩子到了彩虹所在的地方，一个孩子偷了彩虹金子，这导致世界失去了颜色。

Rainbow is about these children who follow the whereabouts of a rainbow. One of the kids steals the rainbows gold (yes! The rainbows gold) and this causes color to drain from the world.
