Colour Shadow Apparatus – RGB Light Mixing & Shadow Demonstration Model
The Colour Shadow Apparatus by ELMO Agencies is an advanced educational optics model designed to demonstrate the principles of additive colour mixing and coloured shadow formation. Using Red, Green, and Blue (RGB) LED light sources, the apparatus provides a clear visual understanding of how different wavelengths of light combine to produce new colours and unique shadow effects.
Widely used in physics laboratories, STEM learning centres, science exhibitions, and educational institutions, this apparatus transforms complex optics concepts into engaging hands-on experiments.
As a trusted scientific manufacturer in Ambala, ELMO Agencies supplies premium educational and laboratory equipment that supports interactive science learning.
What Is the Colour Shadow Apparatus?
The Colour Shadow Apparatus is an optical demonstration model that uses three coloured LED light sources—Red, Green, and Blue—to illustrate the principles of additive colour theory and shadow formation.
When an object is placed between the light sources and a screen, multiple coloured shadows are formed. Students can observe how different colours combine and how the absence of certain wavelengths creates unique shadow patterns.
The entire system is housed in a durable wooden box with an inbuilt power supply, making it convenient for classroom demonstrations and laboratory use.
Working Principle
The apparatus works on the principle of additive colour mixing.
The three primary colours of light are:
🔴 Red
🟢 Green
🔵 Blue
When these colours overlap, they create:
🟡 Red + Green = Yellow
🟣 Red + Blue = Magenta
🔷 Blue + Green = Cyan
⚪ Red + Green + Blue = White Light
When an object blocks one or more light sources, coloured shadows appear on the screen, demonstrating how light interacts and combines.
