Visual experience is painted in color. A change in hue or saturation can dramatically alter our understanding of a scene and how we feel about it. Subjectively, color does not feel like an optional dimension to be extracted only when necessary, but an automatically represented property of our entire visual field. Here, we ask whether that subjective impression is true. Using a variant of an inattentional blindness paradigm, we showed observers snapshots of colorful scenes when unbeknownst to them, an image was presented that was either desaturated or hue rotated across an overwhelming majority of the images. Although observers fixated on these images long enough to identify and describe them, a large number of observers were completely unaware of these drastic color manipulations. These findings suggest that the amount of color observers perceive "in the blink of an eye" is drastically less than personal introspection would suggest.
视觉体验是有颜色的。色调或饱和度的变化可以显著改变我们对场景的理解以及我们的感受。主观上，颜色并不是一种可选的维度，只有在必要时才会被提取，而是我们整个视野中自动呈现的属性。在这里，我们要问这种主观印象是否正确。我们使用一种无意识盲视范式的变体，向观察者展示彩色场景的快照，而在他们不知情的情况下，呈现的图像要么是饱和度降低，要么是色调在绝大多数图像中旋转。尽管观察者长时间注视这些图像以识别和描述它们，但大量观察者完全没有意识到这些剧烈的颜色处理。这些发现表明，观察者“眨眼间”感知到的颜色数量远远少于个人内省所暗示的数量。
