Not possible to add a list of all colors/filaments I have in Bambu Studio?

I'm new to 3D printing. I bought an P1S without AMS.

I struggle to understand how working with multiple colors work, more specifically how to tell Bambu Studio what I have.

I expected there were some place I could just add every filament I have. Meaning, one for each type and color.

I found the UI to be very confusing about this. I see I can make a profile, am I supposed to make a profile for each color and just write the color in the name I save the profile to? But I can't see where I select the color?

Anyone can enlighten me on how this works?

Basically, when I change from black to blue. What should I do in Bambu studio after I have loaded it to the printer?
