Section 1.1: The Role of Cones in Color Detection

Each cone transmits signals to the brain, which interprets these signals and determines the colors we see. For instance, if blue appears weak while green and red are strong, our brain perceives the resulting color as yellow. Still skeptical? You can easily test this fascinating concept using three light sources: red, green, and blue. When combined, what color emerges?

You’ll likely see yellow. This occurs because your eyes detect signals from both the red and green wavelengths. It’s the combination of these colors that your brain interprets as yellow. Such simple experiments can be endlessly repeated, showcasing how light mixes. For example, combining red and blue yields purple, while red and yellow create orange. Yellow and green blend into light green.

Subsection 1.1.1: Exploring the Spectrum

You may wonder just how many shades the brain can recognize. Scientific estimates vary widely, from 150 fundamental colors to as many as 15,000. Some researchers even suggest there could be millions of color variations, influenced by factors like brightness, tone, and saturation. The subjective nature of color perception makes these figures both astonishing and difficult to confirm.

Section 1.2: The Subjectivity of Color

Cultural and emotional contexts further impact our interpretation of colors. Remember the viral internet debate about a dress? A more recent example involves flip-flops. Some perceive them as a brownish-gold, while others see them as blue. The manufacturer claims they are black and blue. Who is correct? Ultimately, the perception of color is a highly personal experience.
