Fallback link is hard to read if the site uses a background color on links

[cbirdsong]

Our theme has a little color tint when you hover over a link:

That also applies to the .lite-youtube-fallback link if the lite-youtube script fails to load:

Easy solution:

• also apply the background color with !important

Complicated solution:

• stop changing the link color, and instead generate the background color from it by using some of those fancy new CSS color functions: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_colors/Relative_colors

!important feels quite appropriate for this case. I'll get that on the roadmap.
