Austin Rurda: 作为一名视光学和视觉科学教授,我很荣幸成为世界上第一个看到一种全新颜色的科学家,这种颜色名为Olo,它并非自然界固有,而是在实验室中通过精确的计算和激光技术创造出来的。Olo是一种比自然界中任何青色都更加饱和的蓝绿色,为了创造这种超饱和的颜色,我们团队采用了一种名为Oz的技术,灵感来源于电影《绿野仙踪》,旨在唤起一种全新的色彩感觉。我深知,每个人体验颜色的方式都有所不同,而色盲患者则因为基因的缺失,所看到的世界也与常人不同。为了创造Olo,我们必须绘制出视锥细胞的精确图谱,并精确刺激M视锥细胞,最终,我们成功地创造出了Olo,并用二进制代码010为其命名。虽然无法用颜料复制Olo的饱和度,但艺术家们通过其他方式,如添加荧光成分,来唤起人们对Olo的感受。虽然动物的视觉系统与人类大相径庭,它们所感知的颜色也与我们不同,但我相信,通过对Olo的研究,能够加深我们对颜色视觉的理解,并为未来的视觉科学研究开辟新的道路。为了让大家体验到Olo的感觉,我建议大家可以先看一段时间的红光,然后再看绿光,这样可以近似地感受到Olo的色彩。

Chapters
This chapter explores the nature of color perception, explaining that it's a complex interplay of light, our three types of cone photoreceptors, and brain processing. It also highlights that individual experiences of color can vary due to differences in cone types and the possibility of color blindness.
  • Color is a complex process involving light, cone photoreceptors, and brain interpretation.
  • Humans have three cone types (L, M, S) sensitive to different light wavelengths.
  • Brain processes subtle differences in cone excitation to generate color perception.
  • Colorblindness results from missing one or more cone types.
  • Individual color perception varies due to unique cone arrangements.

"Olo" does not exist in nature, nor can it be found among paint cans. But for a very select few, olo can be seen — through the intervention of careful computing and lasers. A team led by vision scientist Austin Roorda) and computer scientist Ren Ng) at UC Berkeley figured out a method for stimulating only one specific subset of cones of the retina. It's the only way to view this spectacular teal. Creating the color is helping push the boundaries of vision science.*Follow Short Wave on Spotify), and Apple Podcasts).More questions about the science behind our everyday lives?
