background color different on webserver than on local host....

I work in dark mode with a the backgorund color #000916. When I run the site on my laptop it comes out as such. When I run on the webserver of my provider it turns out as #000508.

What do I miss?

The code in the style sheet is:
[data-bs-theme=dark] {
color-scheme: dark;
--bs-body-color: #dee2e6;
--bs-body-color-rgb: 222, 226, 230;
--bs-body-bg: #000916;
--bs-body-bg-rgb: 00, 09, 22;

Thank you!

problem "solved". A very old css was still in the cache of my browser...

sorry to bother you
