SC 2022-02-19 Feeling Blue

I'm blue da ba dee da ba di
Sophia’s in a blue mood, so the challenge she put forth is this: make a starry corridor entry that is as blue as possible! The elements can be any shade of blue, but they have to be blue blue. The only limitation is you CANNOT use items that are water-themed, and if you can help it, try to avoid using blue-green items (pieces that appear more green than blue).
