Why are some object names in the hierarchy tab appearing blue colored and the others grey? I never actually paid attention to it but noticed it today and couldn't figure out the reason behind it.

Those are prefabs.

“Objects created as prefab instances will be shown in the hierarchy view in blue text.”
