community this is my first question in the forum. Of course, I have been trying to find the answer for quite some time before posting, and nope, the setting I am looking for is not in the THEME tab from the settings menu in Blender.
By the way, I am using Blender 2.82a, and the problem is that I have a light blue color that interferes with the white letters in the graph editor's transform channels and it's hard to read(I have noticed most likely everyone has dark gray background), Please take look to the image.
