Accessibility in mind: All colors used clear the minimum AA accessibility contrast ratio of 4.5:1, while most of them also clear the AAA contrast ratio of 7:1.

Download instructions

  1. Install Tampermonkey for your browser. (Instructions).
  2. Click this link to install Codeforces dark theme userscript.

In case the script is updated later, you need not revisit the page. Tampermonkey auto fetches new updates every 24hrs by default.

In case you're getting this warning:

Apps, extensions, and user scripts can not be added from this website.

This warning is mainly to prevent vulnerable users from installing malicious extensions and apps. In my case, you can trust this userscript as its code is posted on GitHub, under public scrutiny. So, you can safely ignore the warning and proceed with installation.

Notes

  1. Rating color adjustments: User handle colors needed to be reworked to be nice with the latest dark theme. That means the following colors now appear only ever so differently, but the sharp eyes amongst you may notice ;) These color adjustments are only meant to improve contrast ratio of text against a dark background.

    users original color new color
    admins, non-rated, first letter of legendary black (#000) white (#fff)
    Grandmaster red red #ff4747 #ff4747
    Candidate master violet violet #ce8aff #ce8aff
    Expert blue blue #757dff #757dff
    Specialist cyan cyan (#03a89e) #01bdb2 #01bdb2
    Pupil green green (#00d700) #00c700 #00c700
    Newbie gray gray #8c8c8c #8c8c8c

    To view all the color changes at once, view the table on the blog post "Second Revolution of Colors and Titles".
