I have full confidence in you! As a blue heart 💙, this emoji often represents deep feelings of friendship, loyalty and faithfulness between people. At the same time, it can also be understood as a sign of mutual trust and support. It symbolizes love for water sports and appreciation for nature, especially the sea and rivers. In addition, it is used as a symbol of support for autism awareness initiatives to express solidarity and understanding. In a less personal context, brands use the blue heart to spread positive vibes without resorting to romantic or passionate associations.
