挺有意思的文章,但感觉有点水,讲了Karl Gegenfurtner买橙子被骗,看起来成熟且颜色鲜艳的橙子从橙色网中拿出来以后橙子变成了绿色,然后研究发现是颜色同化现象导致的,于是发了篇文章讲了下颜色同化现象的研究历史和一些例子以及一些原理。
文章讲的比较浅自己查了下关于颜色同化现象相关的原理,有三个方面的因素:视觉神经机制因素、认知与心理因素、光学与物理因素。个人感觉视觉神经机制因素应该是影响最大的,主要是神经的侧抑制:相邻的神经元之间存在相互抑制的关系,当一个神经元被激活时,它会抑制周围相邻神经元的活动。在颜色感知中,侧抑制机制可以增强颜色边界的对比度,同时也可能影响颜色在空间上的扩散和同化。例如,在一个颜色区域周围,如果存在与之不同的颜色,侧抑制可能会使边界更加清晰,但在某些情况下,也可能导致颜色在一定程度上向相邻区域扩散或同化,使得边界附近的颜色感知发生变化,从而导致颜色同化现象。挺有意思的一个对日常生活现象解释的知识。

Perceptual ripening of oranges

Abstract:
We present a practical example for the phenomenon of color assimilation. We describe the advances in research on color assimilation from von Bezold, to Albers and Munker, and provide a compelling example of the recently described “Confetti-illusion” by Novick. Our research introduces a novel aspect by showing how unripe and greenish looking oranges can be perceived as ripe and vibrantly colored when viewed through an orange net. These findings highlight the significant implications of color assimilation in everyday consumer environments, offering a fresh perspective on how visual perception can be manipulated.
