Why does it have seven colours? And what have rainbows symbolised in mythologies and art?

Alexandra is a colour expert, art historian and museum curator. Her exhibition 'Colour: A Chromatic Promenade through the Royal Pavilion' is on display at The Royal Pavilion in Brighton until October 2025. She is also author of 'The Artist's Palette' and 'Colour: A Visual History'. Joseph is a Principal Scientist at the National Gallery. He brings a wealth of expertise across multiple domains, including data management, digital infrastructure, conservation documentation, digital imaging, web development, preventive conservation, museum lighting, colour science, and the technical examination of paintings. ----- Watch the full episode on YouTube: https://youtu.be/XjaFKMexByg You can email us with any questions via podcast@nationalgallery.org.uk Find out more about the podcast on our website: www.nationalgallery.org.uk/podcast ----- To take our short survey about the podcast please visit: https://www.nationalgallery.org.uk/podcast ----- Paintings mentioned: Angelica Kauffman RA, ‘Colouring’, 1778-80.
