Sea of cerulean
What's the color mostly associated with the ocean and other bodies of water?
Why blue of course.
It's the color one sees when diving in the vast and opean ocean.
Ethereal galaxy
Gaze upon the cosmic expanse of blue accented by the red to create the beautiful galaxy seen here.
Stay a while, you may find peace here.
Shimmering city
This city's night sky looks wonderful by itself and is made even better by the blue light eminating from the city building giving life to the night.
