I had my first observations of colour in a convent in Granada called Las Esclavas, where as children we were prepared for communion. Rays of light shone through the stained glass windows onto the clean bald heads of the worshippers at the Nocturnal Adoration. There were spheres and ovals, green, blue, yellow, violet and red, and my thoughts followed the changes in the movement and colour on those bald heads, tired from a whole night of worship, and finally with the coming of dawn we went to Mass and the rays of light illuminated us all.
