Alacritty terminal text is always the same color

Question

I've started configuring my alacritty.yml file, making adjustments such as customizing the window dimensions, setting the font style to FiraCode (even though I didn't find how to set ligatures on), and applying a theme from tokyo-night. However, I'm encountering an issue where my terminal text is consistently white, and the overall interface doesn't look like I want.

I've seen others have different symbols for actions like searching (e.g., "~" or "->"), and distinct colors based on the type of action being performed. I aspire for my theme to resemble the ones from here. I've searched and found if you configure the PS1 in bashrc will do the job, but dosen't seem to do anything. Here is my alacritty.yml file:
