Good job preserving the HN spirit!

My only feedback is the gray text (#808080) on the dark gray background (#222222), has a contrast ratio of ~4:1 which some people may find difficult to read (and slightly below WCAG recommendation for regular text[1]). I think you can lighten the text slightly without disrupting the surrounding color hierarchy.

Contrast ratios that are mathematically derived are not always nice or correct. It's notoriously hard to determine perceived brightness from hex codes. That said, it might need some tweaking. I only spent a little time on it and I know it helps to revisit a color scheme a couple of times during different light circumstances.
