Text color issue?

Hello, I'm new to the forum site ownership and I'm having a slight issue I am hoping someone might be able to help me out with.

I'm in the process of setting the site up, got the theme and everything set, for reference the background of the site is black and the text is white. While setting up a thread for guidelines of the site I went to make a spoiler and where it says to enter the title of the spoiler the text is white. It still appears in the editor as black but in the drop down box it's white on white. It took me 30 minutes of messing around with the colors to figure out that it was tied to the base text color of the site.

I am hoping there is a way I can change the text color in the drop down without having to change the theme of the site by changing the color of all the text. Any help would be appreciated.

hello
