Colour

Synopsis

Looks at how a particular combination of visible wavelengths reaching the eye is interpreted as a particular colour. Trichromacy is shown to be the basis of colour vision from Young’s overlapping colour experiment and from modern microspectrophotometry of cone cells in the retina. The difference between absorption, transmission and reflection is made clear by showing absorption of spectral colours by a dye and by cloth coloured with the dye. Finally there is a case study which explains why a carrot appears orange.

Notes

NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
