I don't know where to change the color, it should be gray
if you are refferring to the Normal Mod and Advance Mod, you should edit them from the codebuttons template.
regarding the drop down menu this is the text used for form.
in the theme manager if you scroll till the bottom , you will find Form Elements

I was refferring the white color. I want to change it to gray
There's no white so I quess you mean the bright gray.
You can change the color in the template codebuttons.
