はじめまして。

下記のソースは、所謂"マウスストーカー(時計)"を引き立たせるために  
背景色と組み合わせたものですが、それぞれの背景色に応じて任意に  
"date color"・"face color"・"hours color・"minutes color・  
"seconds color”を変えられるようにしたいのですが、なかなか  
うまくリンクできません(＊普通の文字は、変わります)。

どこを，どのように書き換えればよいか、ご教示いただけませんでしょうか。

question
javascript html
背景色に応じて、時計(の針，など)の色を変えるには？
背景色が変更された際に、各色を更新するようにしてみました。  
こんな感じで良いでしょうか。

日付部分にフォーカスして回答します。

日付部分の色は以下のコードで指定されています。

```

    dCol='blue';   //date colour.
    
```

`dCol`を使っているのは以下のコードです。

```

    document.write('<div id="_date'+i+'" class="css2" style="color:'+dCol+'">'+D[i]+'<\/div>');
    
```

どうやら上記のコードでHTMLを書き出して日付部分を表示していることがわかりました。  
そして、ご丁寧に`id`が指定されていますので、以下のようなコードで文字色を変えることができるだろうというアタリをつけることができます。

```

    document.getElementById('_date0').style.color = "white";
    
```

`id`の数字部分は`0`から`D.length - 1`までのようなので以下のように書けます。

```

    for (var i = 0; i < D.length; i++) {
        document.getElementById('_date' + i).style.color = "white";
    }
    
```

このようなコードを`color1`関数などに入れることでご希望のことができるかと思います。

途中までですが、ここまでのことを整理したコードをjsdo.itに載せておきましたので、ご参考にしてみてください。
