## Emergence
**Emerges from:** [light](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-light.visual), [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [color](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-color.visual), [like](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-like.similarity), [sun](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-sun.celestial), [interaction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-interaction.process), [visual](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-visual.perceptual)

**Through:** light and matter interact through mutual change, producing a visual property in a pattern similar to sunlight

**Novel properties:**
- yellow visual quality
- sun-like hue perception
- distinct color signature

## Examples
- The surface of the Sun emits light at wavelengths peaking around 580 nanometers, perceived as yellow by human vision. *(astronomy)*
- A ripe banana reflects light predominantly in the 570–590 nm range, appearing yellow under daylight conditions. *(biology)*
- The paint on a school bus absorbs blue and red light, reflecting yellow wavelengths due to its chemical composition. *(engineering)*
