quero ver lidarem com uma escala de cores dessas:



Onde os nomes são A1, A2,A3, A3,5... B2... C4... D3... e por aí vai...

Isso não é nada.... uma vez vi umas chapas de padrões cores de geladeiras, máquinas de lavar, etc... te falam que são só cores diferentes, em cores tão iguais, que te dá vontade de derrubar o cara no chão, esmurrar o cara até suas mãos sangrarem, e então agarrar a cabeça dele e bater repetidas vezes contra o chão, por até uns dois minutos depois que ele já morreu, e entã se levantar sobre o cadáver dele, e vitoriosamente bater no peito com as mãos fechadas enquanto dá um grito gutural.

Abstract
Extreme natural ambient light reduction, in both energy and range of wavelength spectrum, occurs during the winter season at very high latitudes (above the Arctic Circle or 66 degrees 32' North) that in turn results in increased exposure to artificial lighting. In contrast, during the summer months, the sun remains above the horizon and there is no darkness or night. Little is known about these extreme changes in light exposure on human visual perception. Measuring color discriminations with the FM100 Test revealed that Norwegians born above the Arctic Circle were less sensitive to yellow-green, green, and green-blue spectrum differences whereas they were more sensitive to hue variations in the purple range than individuals born below the Arctic Circle. Additionally, it was found that the Norwegian individuals born above the Arctic Circle and during autumn showed an overall decrease in color sensitivity, whereas those born in the summer showed a relative increase. All participants were adults and their color vision was tested in the same location (i.e., in Tromsø at 69.7 degrees North). These findings are consistent with the idea that there is a measurable impact on colour vision as adults of the photic environment that individuals born above the Arctic Circle and in the autumn experienced during infancy, namely a reduction in exposure to direct sunlight and an increase in exposure to twilight and artificial lighting.

Got the blues? You can still see blue: Popular paper on sadness, color perception retracted

Abstract

Past research has shown that emotion can influence low-level visual processes, including color perception, that may play a role in higher-order vision. Moreover, the prevalence of linguistic pairings between emotions and color words suggests that emotional experience and color perception may be linked. The purpose of the present research was to test whether emotion influences color perception. We did this by experimentally manipulating emotion with video clips in two experiments (specifically, sadness and amusement in Experiment 1, and sadness and neutral emotion in Experiment 2) and measuring color perception (specifically, accuracy in identifying desaturated colors). The results of both experiments showed that sadness impaired color perception along the blue-yellow color axis but not along the red-green color axis.

We remain confident in the proposition that sadness impairs color perception, but would like to acquire clearer evidence before making this conclusion in a journal the caliber of Psychological Science.
