At first the material has a plain pale green to white colour in normal daylight. However, it builds up a strong yellow green glow while it remains in direct sunlight. This glow effect reveals itself in darkness, where it lights up the metal inside it in beautiful patterns. Raffir Uranium glows because of very fine light-charged colour pigments. Therefore, the material glows stronger and longer the more light it receives. The pigments are of course non-toxic, despite of their strong glow effect. The particular arrangement of the metal mesh in the material creates a stone-like structure.
