>>6621759Lighting and cameras have a lot to do with it. SDCC Broly's hair has a nice shade of green, but if you expose it to just enough light it looks a lot more yellow with a slight hint of green with my crappy phone camera.
A few of the SSJ figures also have fluorescent hair, so they light up pretty bright when they get hit with a blue or black light; like when I turn my TV on at night. My phone doesn't do justice to how vibrant the colors are and it can't even detect some that are incredibly noticable in-hand.
