Answer 1

ColorScheme allows you to define each color property manually.

ColorScheme(
  brightness: Brightness.light,
  primary: Color(0xFF0095FF),
  onPrimary: Color(0xFFFFFFFF),
  primaryContainer: Color(0xFFD3E4FF),
  onPrimaryContainer: Color(0xFF001C38),
  secondary: Color(0xFF006495),
  onSecondary: Color(0xFFFFFFFF),
  .....
);

ColorSchemeSeed generates colorScheme based on one color.
