Google's Material Design Guidelines - the set of design standards they suggest app and web developers follow to keep things beautiful and consistent - have received a February update. Improvements include:
- Expanded guidance on customizing your app’s color palette, with more examples
- Color specs for dialog errors, text selection, and text field labels
- Sticker sheets now include text field colors, month and time pickers, and bottom toolbars (for Photoshop, Illustrator, and Sketch)
