Which one? The listed palette looks nothing like the screenshot on the same page.

Notably, there's no way that light blue for example (which is the default font and border), nor the dark blue (which is the default background).

The screenshot is how I remember the C64, and consistent with other screenshots and photos. The listed hex codes are far off.

The one posted by the person you responded to is a bit muted, but the relative colors seems closer to what I'd expect.
