In science today we investigated how rainbows are created and explored the effect of mixing light of different colours. Here are the sites we used to mix coloured light (which some people wanted to explore further).

We also found out about how we see different colours. Different coloured objects absorb particular light colours and reflect backlight which creates the colour we see. e.g. A red book absorbs all other lights and reflects back only red light. To investigate what colours we see when different coloured light beams are combined, change the ratios of light colours on the site below. It shows you how the colours on early colour computer screens were created with only 16 colours.
