@tothemyers Lol, you are the 9th person who has made one! Good for you! (I am happy, because I made the original a long time ago, but it recently has gotten popularity) and I suggest you make 2/3 blue and 1/3 red: A real purple, not pink...
(How about 3/4 blue? I cannot cut off the sides to make a 3 pixel wide laser because even insulator burns, and that's where the major heat is anyways. I have a solution, but I am still working on it. Idea: Dark INVS is transparent to photons without turning it to neutrons.)
