Adding Color to Obsidian--- A Rainbow of Possibility!

Question: I’m using a light theme. I was able to change the main folder text color to white, it’s readable and has enough contrast. However, I have tried changing the subfolders, as well, but I have not found a way to improve the text contrast on the subfolders. Yes, I have also check with the theme CSS and am still unsuccessful. I will keep working on this, but thought someone here might have a suggestion.
