Thank you, I am getting much better results now that I have Windhawk and some mods installed. For the sake of other people who are curious about the results, I'll post some screenshots.
So for fellow peeps like me who are still curious about WindowBlinds work, something that may come up is that your OS's default light or dark mode will still show up as the background of your file explorer's home window.
However, visiting any other page in the explorer gives the proper theme coloring.
I'm okay with this result, and I'm grateful for the help given to a total newbie like me. I was able to download the new Embellish style from your excellent website, LightStar, and I hope you have a wonderful day.
