Hello!

I've found the text of the blog posts is too light and thus hard to read for weak-sighted people like me:

https://rust-gcc.github.io/2023/04/24/gccrs-and-gcc13-release.html

I've made a pull-request for everyone using the jekyll-theme-minimal (pages-themes/minimal#284), but it would be nicer if the author of this repository changed the color theme of the repository.
