How should I represent the conjugate of a term in the denominator?

Using overline for a term in the denominator creates a cluttered look, and Bar results in a really faint line. Also I only know how to use Bar over one letter at a time.

documentclass{article}

usepackage{amsmath,amsfonts,mathtools}



begin{document}

begin{align*}

frac{z_0 - z_1}{overline{z_0 - z_1}} +

frac{z_0 - z_1}{Bar{z}_0 - Bar{z}_1}

end{align*}

end{document}

I want to have a line that doesn't clash with the fraction line, but that also doesn't require squinting to observe. What are your recommendations? My best idea right now is to color the line gray, but I don't how to do that.

Edit: Actually, a thin line over the whole term, similar to the one produced by Bar, might just work.

Not so good solution, but.... frac{,z_0 - z_1,}{overline{z_0 - z_1}}

Wait a minute... overline{z_0 - z_1} = bar{z}_0 - bar{z}_1 (if these are complex numbers) and hence the whole expression simplifies to 2 frac{z_0 - z_1}{bar{z}_0 - bar{z}_1}.

@HenriMenke The expression is meaningless I just wanted to demonstrate two styles of depicting the conjugate of the denominator. I suppose I shouldn't have separated the terms with a plus sign haha.
