In Deep Ocean, the "identifier under caret (write)" is not readable

[Gouvernathor]

Describe the bug
As stated in the title. The read occurrences of an identifier are correctly visible, but the write occurrences are almost invisible against the dark background.

To Reproduce

    void f() {
        final int a = 0;
        final int b = a;
    }

And put the caret on either occurrences of a.
