To Reproduce
Steps to reproduce the behavior:

Additional context
Maybe its because it dont detect the colors and only a white theme ( but i don't use it weird)

So you're missing the colors when replaying with the js player on your html page?

[yodatak]

Yes I'm missing colors and the file don't show blue color of my default prompt and I canot understand why it don't record my prompts colors

Do you use the latest version of the player? (don't forget about updating the CSS file too)

Support for original terminal colors was added in one of the recent versions of the player.
