Easy improvements for beautiful UI: duotones
Users are heavily influenced by both content and visuals. So, by improving your look, you are actually making your content more effective as well. Use duotones to create sleek, sexy UI like these companies do:
Canva
Canva uses a gradual color gradient to create a beautiful yet subtle backdrop for their onboarding process.
Dude Calendar
Dude Calendar uses a bright, bold duotone with contrasting text to capture and intrigue their users.
Adaptable
Adaptable uses a combination of bright duotone with contrasting text to both capture user interest and subtly highlight the background image.
