where is the css var --b2 and --bc coming from?

[lsbyerley]

Doing a search for them in the repo yields no results, just curious what values they are. I've noticed they are used for the background of cards in the daisyui docs

[saadeghi]

See this table for details: https://daisyui.com/docs/colors/
There are 3 shades of base colors that can be used for backgrounds.

• base-100 (--b1)
• base-200 (--b2)
• base-300 (--be)

And base-content (--bc) which is used for the content or text.

If b2 and b3 are not specified in a custom theme, they will be darker shades of b1 automatically. And if bc is not defined, it will be an opposite contrast of b1 color.
