voonchung Hi
These colors are declared by variables in LESS file: root/templates/ja_intranet/less/variables.less
For example, with 'Brand primary color':
// Brand colors
// -------------------------
@brand-primary: #4275f4;
@brand-secondary: #34bf49; // T3 Note: Add secondary color
@brand-success: #5cb85c;
@brand-warning: #f0ad4e;
@brand-danger: #d9534f;
@brand-info: #5bc0de;
and change the color as you wish. Then compile less to css, you can follow this guide for how to compile: https://www.t3-framework.org/documentation/bs3-configuration#compile-less
Always remember to backup your site before compiling.
Regards
