Harmonies plugin issue

[jfagan1]

I think there is an issue with the harmonies plugin for specific input values. For example if I start with certain hex values sometimes the result returned is slightly off. For example:

const color = colord("#03FF84");
color.harmonies("complementary").map((c) => c.toHex()); // ["#03FF85, "#FF037D"]

You can see that the original color changes from #03FF84 to #03FF85. This problem happens on all harmonies for this color: tetradic, analogous etc. I took a quick look at the source code and I suspect some kind of rounding might be occurring. Does anyone know a way around this?
