Recommended dark mode palette with grey base and SleekFlow blue as accent Base / neutral colors Main background: #111B21 Secondary background: #202C33 Card / panel background: #1F2A30 Hover / active surface: #2A3942 Border / divider: #374248 Text colors Primary text: #E9EDEF Secondary text: #AEBAC1 Muted / disabled text: #8696A0 Accent colors inspired by the SleekFlow logo Primary accent blue: #0568FE Accent hover blue: #1C78FF Soft accent blue: #4F94E0 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
