Suggested usage

Use grey/charcoal tones for the overall interface background, sidebar, cards, and chat surfaces

Use blue only for primary actions such as buttons, selected tabs, links, highlights, and key interactive elements

Avoid using blue as the full-page background to keep the UI cleaner and more balanced

i believe most of the dark mode in any application such as WhatsApp, facebook n instagram they try to keep the UI in a dark mode with a neutral grey base, while using their own inspired color only as the accent color for branding and interaction
