Researchers at MIT and Penn State University have discovered of a new way to produce bright and vibrant colours by shining white light on to small water droplets on a clear surface. 

It is thought that the technology could be used for the production of sustainable and environmentally-friendly colour changing displays, sensors and inks. 

The innovation comes at time of great change across intellectual property law, with many jurisdictions amending their out-dated legislation to reflect the varying and complex nature of modern intellectual property assets. For example, the UK has recently brought into force the Trade Marks Regulations 2018, which expand the scope of what may be registered to include (among other things) colours. 

The inclusion of colours in the new Trade Mark Regulations is indicative of a wider trend towards the recognition of the ways in which colour can be valuable to a business. 

It remains to be seen how this new structural colour discovery will be monetised, although it is safe to say that its development will be watched with eager interest.
