The Material Design color system supports alternative colors, which are colors used as alternatives to your brand’s primary and secondary colors (they constitute additional colors to your theme). Apps can use alternative colors to establish themes that distinguish different sections.
Alternative colors are best for:
- Apps with light and dark themes
- Apps with different themes in different sections
- Apps that exist as part of a suite of products
- Alternative colors should be used cautiously, because they can be challenging to implement cohesively with existing color themes.
