Meaning of 'すれ違う赤の軌道'


I don't really get the meaning of this line 'すれ違う赤の軌道' Could it mean 'Crimson
path crossed' or 'The crimson path i crossed' ?

Words:

> すれ違う: Two things passing or missing one another. In my opinion this can have
> a romantic or at least emotional connotation, as in "so close, but so far!"
>
> 赤: red
>
> 軌道: orbit, often the orbit of a planet or other celestial body

The link given by Tommy (converted to a comment) is a good start, but the
translation is somewhat non-literal.

A slightly more literal translation of this part could be:

> Red orbits, passing either other by
