Background defaults to purple?

[bryiac]

When you don't explicitly set a background it defaults to purple is there any reason for this?

So... there are no default values, and the thing that lands in your CSS is actually background-color: background.
It's just "unsupported" on Theme UI side. I think the library expects you to have a background color.

As of why is background rgb(99, 99, 206)... I tried googling it, but I didn't find any explanation.

that's really weird I honestly thought it was theme-ui making it purple thanks for the response

We have to use the key if we don't find the value, because we don't prefix design tokens in any way, and instead of "background" you could pass "blue", which could be both an HTML color or your theme color.

This is what happens with the default body style... and it turns out that background is purple.
