So you have decided to go with nail polish. Good Choice. The first scrape or two and it peels right off and you start sparking.

But even if anyone choses heat shink. Here is a suggestion. Go with a color like royal blue or any other bright blue color.

Why you might ask? Blue other than water, sky and the occasional flower is hard to find in nature. Even the neon pinks, greens and yellow let alone red can be very hard to spot in grass or fallen leaves. Try it sometime with various colored objects especially something as small as a fire steel. This vanishing act is more prevelent at various times of year or different settings.

But a bright blue being a more unnatural color will supply more contrast if it is dropped or layed aside.

Why take chances.
