I'm currently building a desktop app and decided to go with dark UI. I got really inspired by the tools I use for web development (mainly Atom text editor) which have nice dark UI designs. So I started designing in Adobe XD and I'm currently happy with my UI design. But...
I have noticed that the gray colors I used in the design are purely gray with no tint of any other primary colors, which is not the case in almost all dark UI designs that I have seen so far.
Let's compare my colors to Atom text editor.
Atom's background: #2c3037
Atom's side panel: #262a2f
My background: #262626
My side panel: #1E1E1E
Atom's colors both have a slight tint of blue in them while mine has none, absolutely gray.
So my question is: Is there a reason/theory to choose dark colors like Atom's? What is the connection between the tint in the gray and the choice of the designer?
I would appreciate any guidance.
