Audition 1.5 I can darken the waveform colour in edit mode but not multitrack

[Mygeneration]

The subject pretty much sums up my problem. 

I'd like to darken the waveform colour and it works in edit mode however in multitrack mode iwhilst the colout changes it stays stubbornly bright - in fact it seems like there is only version of each colour in multitrack

Hello-

You can go to settings, open colors, then select Waveform. There is a list beneath, where you can select Waveform Foreground. It's here where you can select different colors and shades for the multitrack window.
