Hey @CodeF53

I really love this. However, I think this came at a really unfortunate time for contributions. Much of the official artwork has been migrated to the new nixos/branding repository and as such this repository will soon be publicly archived (see #155).

I had already had played around with adding a trans variant of the logo when building up the branding repository but put it on hold because there was already an enormous amount of work. If you would like to open an Issue in the branding repository requesting a trans variant of the logo, I'd be happy to add it to the official set of artifacts when I have time. You are also more than welcome to submit a PR but there is a non-trivial amount of tooling to become familiar with. Totally up to you. Let me know if I can be of any help.
