I had a longer post but realized the answers to one of my questions so here’s the abbreviated version!
It is quite annoying that whenever I open Firefox Color it instantly changes my theme to whatever my Firefox Color theme was the last time I opened it, and I can’t find any way on Firefox Color to just stop wearing a theme. Like, I just can’t find a setting anywhere on Firefox Color to just not wear any Firefox Color theme. The only way I can find to get rid of a Firefox Color theme is to enable another theme. It is very annoying and makes me not want to even open Firefox Color because it will create a hassle to go back to the theme I was using before.
