Looking in the choices for the console view in preferences > colors....., I'm not seeing how to darken it a tad. Track view there were 4 or 5 presets and the "dark" worked for me. That didn't seem to affect the console view.
That said, I actually like the color scheme of the grey, while I know many don't. I DON'T want this thread to be a gripe about colors however. But brightness is an issue sometimes.
Also...I DON"T want to adjust my monitors, as the ones that I have (ViewSonic 27") are very near my active Yamaha audio monitors, and by keeping the brightness UP on the video monitors, keeps the Yamaha speakers from humming away like a bees nest.
Hence my desire to darken my color schemes in Sonar.
