Code block can't correctly display python variable color

[Wannabeasmartguy]

Hello! Things is the best theme I've ever used! However, during my usage, there's a problem(or feature?) border me a lot:

When I'm in edit mode, things correctly renders the corresponding colors of variables, entities, and functions in python.

But when in reading view, they all turn red.

I've located the code block below, but I'm not sure how I should modify it, as I only know a little bit about css, but am not familiar with it.

code[class*='language-'],
.token.selector,
.cm-tag,
.token.dom.variable,
.token.tag,
.cm-def,
.token.parameter,
.cm-property,
.cm-qualifier {
  color: var(--atom-red);
}

If you give me a suggestion, that could be of help!
