The Science of Color Perception and Symbolism
TLDR Color is our perception of visible light, which is created by the pigments in objects that absorb certain wavelengths of light and reflect others. Color perception varies among individuals and is influenced by personal experiences and culture, while certain colors have universally symbolic meanings.
Timestamped Summary
00:00
Color is our perception of a specific wavelength of visible light.
04:19
Visible light is part of the electromagnetic spectrum, and within that spectrum, there is a narrow slice of light that we can see, which includes the spectral colors like red and blue, and the colors we perceive are due to the pigments in objects that absorb certain wavelengths of light and reflect others back to us.
08:48
Color does not exist without being perceived, and we see color through specialized cells in our eyes called cones that are attuned to different wavelengths of light, allowing our brain to mix these colors and create the colors we see.
13:21
The human eye can perceive around 10 million colors, which are created by the red, green, and blue cones in our eyes and adjusted by our brain.
17:45
Color perception varies among individuals, and colorblindness is a result of the brain's inability to distinguish certain hues, not a complete absence of color or seeing everything as gray.
22:20
The primary colors for additive systems are red, green, and blue, while subtractive systems use cyan, yellow, and magenta, which have replaced the traditional primary colors of red, yellow, and blue in painting and printing.
27:11
Complementary colors are contrasting colors that create a neutral color when placed together, and when you stare at a bright red spot for a minute and then look at a white surface, you will briefly see green due to retinal fatigue.
31:24
Color preference and symbolism is highly personal and based on past experience, upbringing, and culture, which is why color psychology can be difficult to apply universally.
35:53
Color preference and symbolism can vary across cultures, but there are some colors that have become universally symbolic, such as red stoplights, and certain colors can have general mood effects, like blue being calming but also potentially depressing.
40:28
The sky appears blue because the angle of the sun scatters blue wavelength light more than other colors, while reds and yellows appear during sunrise and sunset due to the scattering of blue light.
