**Chennai, India** – The Hindu newspaper’s online quiz, published January 24th, 2025, tested readers’ knowledge of color perception and related phenomena. The quiz, focusing on the science of color, posed five questions covering various aspects of visual experience, including synesthesia, color illusions, and color theory.
One question asked readers to identify synesthesia (X), a neurological phenomenon where stimulation of one sensory pathway triggers a response in another, such as seeing colors when hearing sounds (chromesthesia). Another question explored the concept of (Y), a visual illusion where perceived colors in an image differ from the actual colors due to an ambiguous light source.
The quiz also delved into the Kruithof curve, a graphical representation of aesthetically pleasing color combinations, and the theoretical concept of (Z), which, though lacking physical existence, is described mathematically in color theory. The opponent-process theory, used to explain this invisibility, was also referenced.
Finally, the quiz touched upon the common phenomenon of afterimages, asking readers to identify the name for this natural occurrence, differentiating it from the disorder, palinopsia. The quiz concluded with a question about the Ishihara test, a common method for detecting color vision deficiency.
The quiz, available on The Hindu’s website, served as an engaging way to explore the complexities of human color perception.
