Technical Specifications
| Specification | Value |
|---|---|
| Red channel | 620–750 nm |
| Green channel | 495–570 nm |
| Blue channel | 450–495 nm |
| Controls | Independent intensity dimmer for each colour |

How It Is Used
The three colours are projected onto the screen and overlapped. Where two primaries overlap a secondary colour appears, and where all three meet the screen looks white. Turning the dimmers changes the mix, showing how the eye perceives white light and other hues from combinations of red, green and blue.
