      Hey Lulu! We have lots in every colour of the rainbow. There are lots of blue ones. Blue conductive inks are really high energy, (like ultraviolet light from the sun is really energetic and dangerous) so they conduct electricity really well. That means if we make light emitters out of them, they burn super brightly. It is amazing! but it also means they will get tired and die quite quickly- lots of research is going in to making sure the blue lights live for longer. Red light emitters are much lower energy (like the infrared light in your TV remote). The blue inks are used for lots of dies in things at home- like the blue colour in £5 notes.
