Theme reject, as duplicate, but not a duplicate

so I made a theme with black background, AND blue text, it was marked as a duplicate of this theme https://addons.mozilla.org/en-US/firefox/addon/blacktheme/

my theme: https://addons.mozilla.org/en-US/firefox/addon/black-gradient-with-blue-text/

that theme uses white text, while mine has blue text. so not a duplicate.
what do I do?

I made the theme to match the text color of my linux theme which uses blue text.
linux theme: https://www.gnome-look.org/p/1080259/

The image is a duplicate. You can use an add-on to make adjustments to text color though.
