editing font colour on a Soho template

[BlueLight]

Hello,

I've just installed the floating menu on one of my sites and everything is fine other than the font colour on the original vertical menu of my template displays as white without any regard to the choice I make through the floating menu plugin. This would not be a problem other than the background on which the vertical menu displays is light gray, so the white on light gray cannot be read easily.

I have gone into the template file HTML and changed the #ffffff to #008080 but I didn't see any change, so reverted the coding to what it was. Does anyone know where I could change the vertical menu font colour on the Curvacious teal Soho template? and could you guide me through the process? I'm pretty good at following directions.

I have already contacted the plugin builder but they have not solved the problem yet, so I'm trying all avenues.
Thanks
