Spinoff on nail polish

[Parfait]

What are your thoughts on two different colors for fingernails and toenails for recruitment? Is this a faux pas or acceptable?

Does it make a difference if it's in the same color range, but only slightly darker lighter?

I generally have different colors for fun, but it's rare that anyone sees my toenails, but for recruitment I'll have open-toed shoes.

Thanks. =)
