For seeing color. Most humans have three types of cones tuned to red, green, and blue. Your brain mixes these signals to "create" the millions of shades you see every day.
When light hits an object, the chemicals in that object (pigments or dyes) absorb certain wavelengths. The colors that aren't absorbed are reflected back to your eyes. A green leaf absorbs red and blue light but reflects green.

Not all color comes from pigments. Some of the most vibrant colors—like the shimmering wings of a Morpho butterfly or the "eyes" on a peacock feather—are caused by . Tiny, microscopic structures on these surfaces interfere with light waves, reflecting only specific, brilliant hues that shift as you move. 4. How We See It: The Biological Finish Line
On a molecular level, color happens when photons strike electrons. If the photon has the right amount of energy, it "kicks" an electron to a higher energy level. The specific energy gap of that molecule determines which color we see. 3. Structural Color: Nature’s Glitter For seeing color
Ever wonder why a ripe tomato looks red, or why a sapphire glows deep blue? Color isn't just an aesthetic choice; it’s a complex interaction between light, matter, and your eyes. To celebrate , let’s dive into the fascinating world of how color actually works. 1. The Physics: Light as a Wave
Should we dive deeper into recreate these colors using pixels, or When light hits an object, the chemicals in
When light passes through different mediums (like a glass prism or a raindrop), it slows down and bends. Since different wavelengths bend at different angles, the white light splits into the classic rainbow: ROYGBIV. 2. The Chemistry: Atoms and Electrons
