Color of modern theme can be symple changed with global tag.
How I can set this in unigui?
Here instruction

Fashion.css.setVariables({ "base-color-name": "blue", "accent-color-name": "orange" });
where put this ???
Also See: https://www.sencha.com/blog/materializing-the-ext-js-modern-toolkit/
Simply change your $base-color-name and Fashion will handle recalculations and set the proper CSS variables
At runtime we can set dark-mode via CSS variable dark-mode ..
PS:
In file
/m/ext-6.5.3/build/modern/theme-material/resources/theme-material-all_2.css
I found root{--dark-mode:true;--base-color:
but change base-color here has not effect
