Primary Colour Kit
Product Code : SCL-LAO-11119
Quick answer: The Primary Colour Kit demonstrates additive mixing of light: red, green and blue light are viewed separately and then overlapped to show the secondary colours and how the three primaries together approach white. It links optics lessons to the RGB principle used in screens and cameras. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the colour mixing experiment is done
Coloured light mixes by addition. The eye has three kinds of colour receptors, most sensitive to red, green and blue, so these three colours of light act as primaries. Where red and green light overlap on a white surface the eye sees yellow, green and blue give cyan, and red and blue give magenta. Where all three overlap in suitable proportions the result is white.
Additive mixing is different from mixing paints, where each pigment absorbs part of the light and the mixture becomes darker. Comparing the two helps students see why the primaries of light differ from the primaries of paint.
- Set the apparatus on a stable bench in a darkened room.
- Observe the red, green and blue light one at a time.
- Overlap two primaries at a time and record the secondary colour produced.
- Overlap all three and note the colour where they meet.

Frequently asked questions
What are the primary colours of light shown by the kit?
Red, green and blue. Overlapping any two gives a secondary colour: yellow, cyan or magenta.
Why do red, green and blue light make white?
The eye has three types of colour receptors. When red, green and blue light stimulate all three in suitable proportions, the brain perceives white.
