color issues

1. If you spawn more than 20 processes, the color would be undefined and logs will look like that:

```
undefined[sinopia out (l0)] //localhost:4873/
undefined[sinopia out (l1)] Server is listening on http://localhost:4873/
undefined[sinopia out (l2)] Server is listening on http://localhost:4873/
```

... and repeating the same colors multiple times just smells bad...

2. Removed black color. I use *konsole* terminal with black background. It's the default, and I believe a lot of people do so. But black text on a black background isn't very readable to say the least.

If you want to use black, please set a light background explicitly.

There might be a way to get around it by querying a terminal background and avoiding similar colors. But it sounds way too complex for the task.

3. I commented out each color to improve readability of a code.
