Aequorea victoria
Houdebine used the GFP gene found in the jellyfish, "Aequorea victoria", that fluoresces green when exposed to blue light. This is a protein used in many standard biological experiments involving fluorescence. When Alba was exposed to such light, she would literally glow green — though photos by Kac showing the entire organism, including its hair, glowing a uniform green have had their veracity challenged.
