Tailwind's Preflight reset resets lists to be unstyled by default. Without a list-disc or list-decimal utility class, lists will have no bullet or numbers. Using the list-disc/list-decimal sets the list-style-type property, which sets the ::marker pseudo-element to be bullets, numbers, or other things. This is the behavior you see in your first example. The bullet is the browser's default bullet.

When using Tailwind Typography, you should not need to use utility classes within the content, and you may run into unexpected issues with conflicting styles/specificity if you do. In Tailwind Typography, lists are styled by default. However, the typography plugin does not set the ::marker pseudo-element with list-style-type. Instead, it uses the ::before pseudo-element, which allows for more control over the appearance of the bullet.

When using Tailwind Typography and the list-disc utility, these two methods do not conflict, since they do different things, so both are displayed. The darker bullet is likely the ::marker pseudo-element set by list-disc, while the lighter gray bullet is the ::before pseudo-element set by Tailwind Typography. Try using your browser's DevTools to see the pseudo-elements, as well as playing around with what properties are being set and how they affect the appearance.

To avoid this duplicate behavior, simply remove the list-disc class from your list. If you need to customize your Tailwind Typography styles, see the Customization section in the docs. You can also poke around in the source to see how the default styles are set.
