Dashboard Device Symbol Color Meanings

I just added another Monoprice Door/Window Sensor to my VeraLite and for some reason this one appears differently on my Dashboard under “Devices”. The first one I installed has red “signal” markings on the dashboard, this second one has grey. Can anyone tell me the significance of this? I attached a screenshot for reference. Thanks in advance for any help!

The red markings indicate the device has tripped. The grey markings mean the device is in untripped state.

Ah I see. That makes sense. So for a device like a door/window sensor I should expect to see grey markings when the door is closed if it is functioning correctly right?
