It shows going to Setup in Salesforce, Themes and Branding in the User Interface, finding Salesforce Cosmos (SLDS2), and creating or using a new theme by naming it and setting branding, dark mode beta, and images for backgrounds, banners, avatars, and logo. The speaker demonstrates their active “Blaze Cosmos” theme modified in 2026, noting chosen colorways, the top-left brand image, accent colors for Web Content Accessibility Guidelines, and rounded edges and clearer widget backgrounds. It also highlights improved pastel notification colors for duplicates and successful record creation and suggests letting users know before rolling it out.
