I have to set backgroundColor of div using RGB values . Im able to get this way.

```
<div style="width: 100px; height: 100px; background-color: rgb(255,0,0)">
</div>

```

Now, Since I also have CMYK (0,1,0.5,0) values , So Can you assist me how to achieve same with these values.

Im doing this way , but no gain .

```
<div style="width: 100px; height: 100px; background-color: device-cmyk(0, 1, 0.5, 0)">
</div>

```

Thanks
