Color is a great way to impart vitality, provide visual continuity, communicate status information, give feedback in response to user actions, and help people visualize data.

• Use color judiciously for communication. The power of color to call attention to important information is heightened when used sparingly.
• Use complementary colors throughout your app. The colors in your app should work well together, not conflict or distract.
• In general, choose a limited color palette that coordinates with your app logo. Subtle use of color is a great way to communicate your brand.
• Consider choosing a tint color to indicate interactivity throughout your app. If you define a tint color that denotes interactivity, make sure other colors don’t compete.
• Provide two versions of your tint color to make sure it looks good in both light and dark modes.
• Avoid using the same color for interactive and noninteractive elements.
• Consider how artwork and translucency affect nearby colors.
• Test your app’s color scheme under a variety of lighting conditions.
• Consider how your use of color might be perceived in other countries and cultures.
• Avoid using colors that make it hard for people to perceive content in your app.
