Colour wavelengths - Science

Electromagnetic radiation

  

Aim: I want to find out how light colours mix together.

 Research: Mixing light colours are called additive mixing. All these colours evolve around wavelengths, the bigger the wavelength the brighter and bolder the colour is. Fact is that, white is made of every colour in the rainbow as it has it has all wavelengths.  

Certain objects appear different colours because of different wavelengths. White appears white because it reflects its own colour. Black appears as all different, dark colours because it doesn't reflect its own colour. This picture you simply see a red shirt and blue shorts, you see red because it reflects off the colours of red, orange and yellow which all evolve around the colour red. Then blue reflects off blue, dark blue and purple. They all evolve around blue! 

There is a difference between on screen colours and real life colours e.g inks and paints. On TV screen most colours mixed together would reflect as the colour black.

While mixing actual paints in real life you will

white instead. Yellow, Magenta & Cyan are the only colours that cannot be absorbed to reflect, instead if you mix those three colours together you will end up with black and no colours will be reflected back. All primary colours can be turned into a lighter or darker version of themselves.
