Can you tell the colour of the hearts? Clever optical illusion is stumping the whole web(and we guarantee you'll get it wrong too)
你能辨別這些心的顏色嗎？巧妙的視覺錯覺在網上火了（我們保證你也會犯錯）。

Yet another optical illusion has popped up on the internet proving how little we know about how our brains work. These two hearts in the image appear to be totally different colours. One appears purple while the other is a bright orangey red.However, the two shapes are in fact exactly the same hue - a vivid pink.
又一組視覺錯覺照片在網絡上出現(xiàn)，這證明了我們對大腦工作的方式了解的少之又少。這兩個心的圖案看起來顏色完全不一樣。一個是紫色另一個是亮亮的橘紅色。然而，事實上，兩個圖案是一個顏色，亮粉色。

These surrounding blue bars make the heart seem purple while these surrounding green bars make the heart appear orange.
周圍藍色的條形圖案使得心型圖案看起來呈現(xiàn)紫色，如果條形圖案是綠色的話，心的顏色就是橘色。

This gives us a vital clue to how our vision works. It suggests that we perceive an objects colour not based on its actual colour but on how it compares to the surrounding colours.
這是一條關于大腦如何運作的重要提示。這表明我們不是基于物體的本來顏色去識別顏色，而是根據(jù)物體和周圍顏色的對比來識別的。
