Can anyone help me find a single bedding set in this colour?

[SquiglePig]

I don't even know what shade of blue it is to search

Try googling dusky blue bedding, brought up a few results for Dunelm that look similar or maybe denim blue

Duck egg, teal? There's quite a range of shades but you should be able to find quite a few.
