A dark blue theme similar to Breeze Dark. Probably one of the more functional themes in Spectrum. If you run into any strange contrast issues, please comment on them so they can be fixed.
This is for use with Spectrum Iolite. For variants, check out the Colors Collection and for pure dark and light themes check out the Eclipse Collection.
