Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

字色突出时背景色就瞎眼背景色舒服时字色就看不见

savor主题就直接去掉了背景色

还有以前就有人吐槽过的警示气泡（如双链的内容块未找到）的颜色也太吓人了。

Expected result

要不设置成别的变量？或者尽量别让b3-theme-error直接当背景色吧
