Apple Watch cellular icon (white)

Yes, the white icon on left. The what I deem to be an antenna inside the white appears black but on my watch it is red and am curious if it’s something I need to be concerned about. Mahalo for your attention to this.

The cellular data symbol in the control panel is white when phone nearby, Bluetooth connected, WiFi on watch connected. If Bluetooth on phone disconnected and cell icon on watch control panel disconnected cellular data symbol turns green (ie no longer in phone range). The antenna color inside the cellular data symbol on the watch control panel color indicates signal watch strength. Watch signal strength less than phone signal strength. Thus, phone may show black antenna but watch red antenna meaning weak or no signal.
