Hi, if you mean the Firefox UI toolbars, open the 3-bar menu > Customize, then Themes (at the bottom of the window) and select 'Light' then click Done to save.

There is also a large number of other themes here: https://addons.mozilla.org/firefox/themes/

If you want to make your own theme, see: https://addons.mozilla.org/firefox/addon/firefox-color/

If you want to change website colours, see: Change the fonts and colors websites use
