Super Galaxy Rumble Visual Bug

Ive noticed that when I use this skin, his electro harpoon (a rocket in this case) starts out orange. When in the danger zone, this rocket is supposed to be a purple. I noticed that whenever I use a harpoon at 40 heat to get me into the danger zone, and then use another harpoon, the harpoon still has the non-danger zone visual. Furthermore, any harpoons I cast afterwards for a period, whether in the danger zone or not, are all the orange regular color. I'm hoping it's just a visual glitch, but I'm also wondering if it isn't applying the extra damage and slow since the visual is off.
