Cue send colo(u)r in mixer different


I can´t find an answer to this in the manual nor here.

Does anyone know why the cue send level (in the mixer) on one track is brighter green than on another track? I know it´s got nothing to do with whether you have selected the track or not.

See the picture for what I mean.

Working in C7.0.5 W7 BTW.

Kind regards, Charles
