vscode extension: color preview

[losting]

Clear and concise description of the problem

could you provide more style options for the color blocks? After getting used to the square color blocks in the Tailwind CSS plugin, the round ones look jarring and seem too large.

Suggested solution

provide more color preview styles or optimize the current style. thank you for all your hard work.
