Sonar x3 changing color of velocity controllers in prv

My eyes and age are getting up there. When I show controllers and view the velocity controllers below the prv view. They are a pale yellow. I was hoping there is some way of changing this color. I use 2 monitors at 1920 x 1080. Things are small enough at that resolution, but the pale yellow for velocity and the thinness is almost impossible for me to see on my monitors. I can go to preference but do not find much on display of colors for the prv view. I'm probably ignorant to the term that identifies the controller line colors. Anyone else have this problem and has found a solution?
Thanks.
