Step by step
Solved in 3 steps
- Color vision is trichromatic in that 3 primary colors can mix and match all other colors. However, there are 4 unique colors or hues that come in opponent pairs. Name and describe what retinal elements or structures produce trichromacy, compared to what retinal elements or structures produce unique color signals and opponent color pairs?Why is it difficult to see colors in dim light?Explain why different types of receptor cells and neural circuits are required for day and night vision.
