Kind of surprised to see that M3 cards use MaterialTheme.colorScheme.surfaceVariant as their background. Its super bright compared to everything else. And the documentation states that it should use md.sys.color.surface-container-highest. Bug? Feature? 🤷🏽‍♂️

They changed the M3 spec last year. surfaceContainerHighest is the new name for surfaceVariant. M3 in Compose hasn't been fully updated yet.

Ahhh, thanks Sean 🙏🏽 Im still surprised by just how big of a contrast the card color has against everything else in the ColorScheme, even if I use default M3 themes. Its just my opinion though, ElevatedCard colors match what Id expect, so Ill use those.

The web material theme builder hasn't been updated, but the figma version has. It seems free to use. There's a blog post about it https://material.io/blog/material-theme-builder-2-color-match It will generate the new colors for you.
