What is the difference between Polar white and Arctic white boat hatches?

Here is a comparison photo to easily show the difference:

Polar white is the brightest pure white they offer. Arctic white is an off white with a hint of beige. The third color is pure black.

Hi-Tide also makes custom colors for various boat makers with combinations of sand, beige, and grey. You will sometimes see those colors on a couple different items, and typically once they sell out, they are not available again.

Jim Black components, manufactured by Hi-Tide Manufacturing currently offers three stock colors for most of their deck hatches, port windows, ventilation hatches, escape hatches, pontoon doors, and access plates and deck plates. Black, Polar White, and Arctic White.

Great Lakes Skipper is also able to supply hatch handles, risers, gaskets and screens for the Jim Black ventilation and escape hatches as well as port windows.
