31st May - 3rd June 2016, Granada, Spain 

International Conference on "Light and Color in Nature"

The “Light and Color in Nature” conference returns to Europe for the 12th edition from 31 May - 3 June 2016 in Granada, Spain. The 2016 meeting will contribute to the increasing interest in this international conference by bringing together a diverse group of participants at a site to which many cultures have contributed over the centuries. Located in the South of Spain, Granada is anchored by the Sierra Nevada Mountains, the highest mountain range of the Iberian Peninsula and the tropical coast of the Mediterranean Sea. With a deeply diverse history that leads to a present rich in culture, vitality, and acceptance, Granada is the perfect setting to bring together scientists, engineers, students and educators to engage in an international exchange of ideas and discoveries. Along with members from North America and Europe, we anticipate Granada will be attractive to Latin American, African, and Middle Eastern scientists in the field of color and light in nature.

#SOCIAL PROGRAM / Main conference + Excursion



For companions, we have developed an alternative social program that will be compatible with all major social events of the conference: meals, guided tour to the Alhambra, gala dinner and the tour scheduled for the Conference.























  • 31st May


The neighbourhood called Realejo opens the doors of spaces closed for a long time. The visit begins for unknown places as “Camarín de la Virgen del Rosario”, a little Versailles hidden in the city. Later, we will visit to the royal quarter of Saint Domingo, an ancient defensive tower that it inspired the architects of the Alhambra. Finally, we will walk up to Casa de los Tiros and we know the History of Granada Venegas ́s family and other legends connected with the foundation of the castellan Granada. At the end of the walk, we will come back to the venue to have lunch with the rest of the conference assistants and after some free time we will join the final Conference session: Light & Color Official Slide Show "Pretty Picture Session"


  • 1st june


During this visit we will discover what lies behind the facades and walls that hide the interior of the Muslim homes in the Albayzín neighborhood. These residences, or “Carmenes”, constructed according to the philosophy of Muslim space, were first built with the ambition of protecting privacy, and afterwards served as the location for Christian settlement, influencing Granada’s way of life for future generations. Access to its orchards, gardens, and interiors will take us back in time, and will bring an understanding of the historic reality that these genuinely Granada style houses hide and the various ways that they are used today.  After the visit a bus will take us on to the Science Park where we will have lunch with the rest of the atteendees of the conference. After having lunch we will have time to visit this fantastic science museum.

At night, a banquet dinner with a private flamenco show by Juan Pinilla at Peña de la Platería will be the icing on this day. 


  • 2nd June


The excursion day will start by visiting an olive oil mill in the Natural Park of Sierra Nevada where attendees and companions would be able to learn all about the production process of olive oil since the olives are in the trees until they become liquid gold.

After having lunch at the restaurant Jardines de Alberto and enjoying some free time,we will visit the Alhambra. In this visit, attendees and companions will enjoy the most emblematic monument of the city and one of the most visited in Spain, declared a World Heritage Site. Once finished the guided tour, buses will leave us in the same place we were picked.


  • 3rd June


Today we will start by ascending the hill “Cuesta de Gómerez” toward the “Arco de las Granadas” from where we continue toward the Towers where ancient prisons of the Alhambra are described. Next, we will enter the “Rodríguez Acosta Foundation” where we will visit conserved parts of the hidden pathways that were connected to the underground tunnels of the Alhambra in ancient times. The visit will continue in the old "Campo de los Mártires" where, centuries ago, Christian prisoners were tortured in gloomy dungeons until they were rescued by Catholics Kings
