Looks normal to me. Every hobby fuel I have seen is pink, green, or blue. Here is a shot of the tank on my Whiplash nitro helicopter. The fuel is Cool Power 30% helicopter fuel.
If the fuel is clear, it`s most likely because the manufacturer forgot to add the dye. Which had happened with a case of VP Power master I got a few years back. VP is supposed to be blue. But all six gallons in that case were clear. It made for some interesting flights, with some ending in engine off auto rotations, due to running out of fuel.....because I couldn`t see how much I had left.
