'Segredos da Luz e da Matéria - A Cor' is a short documentary produced by Andar Filmes and ETN Audiovisuais under comission from the Coimbra University Science Museum. It's essentially a portuguese language remake of 'Words and Thoughts in RGB' (vimeo.com/832162), with a few errors and omissions ironed out.

Narrated by Inês Mariana Moitas. Sound design by Rui Lima and Sérgio Martins.
