When i bought this insulator off eBay, it cost me a total of 17.25 US after shipping etc. they described as light blue, which is listed at 3-5 dollars in the [080] embossing. After I received it I noticed it was leaning towards Hemi blue, or more correctly Light Hemi blue. I accepted that what was said to be a 5 dollar insulator was closer to being a 1 dollar insulator, and i had paid about 1700 % more than it was booked for to receive it. But i then realized, that it's just a shade off what they described it as, and I forgot about it. Had it been a difference of yellow green to green, i probably would have contacted them. I think those who need/want exact shades of color, should take there light box and drive around, us collectors that don't mind a few shades off now and then will buy what we can from eBay!!
