Learning objects Additive colour: combining coloured light

TLF ID L2543

Shine different combinations of primary colours onto a white object. See if the colour is different from what you would expect to be produced if mixing coloured paints. For example, will combining red and blue light produce purple, magenta or white light? This learning object is one in a series of two learning objects. The series is also packaged as a combined learning object.



Educational details

Key learning objectives
  • Students predict the result when additive colours are mixed.
  • Students explore the range of colours produced by combining different ratios of the three primary additive colours.
Educational value
  • Illustrates the colours produced by combining different ratios of the three primary additive colours.
  • Includes a screen capture mechanism for comparing the results of mixing coloured light.
  • Demonstrates that mixing coloured lights (an additive process) does not produce the same result as mixing paint colours (a subtractive process).
  • Tests understanding of key concepts through multiple-choice questions.
