how to invert every lexer's color

[hycmos]

I set the editor to a black background, and I adjusted my default syntax color to fit the black background.
This way, color display is normal when I open files that I use frequently.

However, occasionally I open other files with different suffix names. The default syntax coloring of these files is to accommodate the white background. So what I see against my black background is very disconsocicial.

How should I set some option so that all colors are reversed.

Thanks.

Why choosing one of the dark themes in "Options > Themes..." didn't work for you?

you can uncheck [x]Sync option in the "choose theme" dialog and choose OK syntax-theme e.g. 'ebony' or 'sub'.
