Lin explains further that while the gene for blue fluorescence is also taken from coral, the hue it produces is barely distinguishable from green to the naked eye. In the future, the search will be extended to crustaceans in the hope of finding a gene for blue fluorescence that provides a greater intensity.
林學廉進一步解釋，目前的藍色螢光基因也取自於珊瑚，但肉眼看來幾乎和綠色沒有差別，未來還要將觸角伸向甲殼類，希望能找到表現強度較佳的藍色基因。
