### Steps to reproduce

* Set your colour mode to Dark

* Go to a work package list where there is an overdue date 


### What is the buggy behavior?

* The red used is:

* a fixed hex in the Work packages list (#c92a2a)

* odd `warn` colour variable in Notification center list


**On a work package table I see:**

```css
.__hl_date_overdue {
color: #C92A2A !important;
font-weight: var(--base-text-weight-bold);
}
```

**In Notification center**, a `--warn` colour variable is used, but it doesn't seem to adapt well to dark mode. I'm not sure where it's coming from:

```css
.op-ian-date-alert_overdue {
color: var(--warn);
}
```

###End of the insertion What is the expected behavior?

* The same colour is used everywhere for overdue dates: Primer token `fgColour-danger` Begin of the insertion

* This needs some additional changes as it would break color harmony in other modes:

* For dates that are today, we use `fgColor-severe`

* For tables, we change the selectionColor to `bgColor-accent-muted` and the selected border color to `bgColor-accent-emphasis`
