Readability issues - thin font weight and text contrast

[polpo]

I don't usually consider text on the web hard to read, but I had issues with the readability of the articles in this series. It seems that the combination of the thin font weight of 300 of the body text with a color of #4d4d4d (contrast ratio of 8.45:1, not too bad actually) is the reason. Anecdotally, increasing font weight improved the readability more for me than darkening the color.

Viewed on a MacBook Pro 14" with display at its native 3024x1964 (254PPI) resolution.

Thanks for the info, solving readability issues has been a tough challenge for me since starting the site, it's also one of the reasons I offer the alternative classic.copetti.org. For your particular issue, could you please let me know more about your setup:

• Do you encounter the same readability issues in dark mode?
• Which browser are you using? (for some reason, some bundle a very thin Helvetica Neue font).
• Is this issue only present on a MacBook Pro 14" screen?
