One of the oldest themes and concepts in myth or storytelling is the idea of the elements, the forces of nature that make up the world around us. Some can control these elements, and those who do are often going to be strongly associated with whatever element they master. However, what about people who are just associated with these elements?
That's where the Elemental Motif comes in. Instead of just controlling the elements, these things are highly associated with these elements, and the story makes sure to point it out. From characters, to objects, to fighting styles, and anything and everything in between, there can be a deep and often metaphorical association with a specific element. After all, a lot can be said about something or someone by comparing it to an element, just as a lot can be said with comparisons to animals. What is being said, however, depends on the subject.
In your case, you have a light motif. Illuminating, warm, life-giving, and colorful, but blinding and illusory.
