About this app
Additive Color Mixing is an interactive science simulation for exploring how colored light combines and how objects appear under different illumination. Toggle red, green, and blue lights to create yellow, cyan, magenta, white, and other combinations, then switch between objects to see reflected and absorbed light. A separate lighting activity demonstrates why a red apple can appear black under green or blue light while white paper follows the light color.
Use cases
- Middle school students learning about light and color
- Teachers demonstrating additive RGB color mixing
- Science classes exploring reflection and absorption
- Learners investigating how illumination changes perceived color
Features
- Toggle red, green, and blue lights independently
- View additive color combinations and current-color feedback
- Compare reflection from a red apple, green leaf, white paper, and black cloth
- Cycle through white, red, green, and blue illumination
- Complete guided missions with reset and next controls
