Setting count makes hue turn red

**Update:** I have run several tests. Setting count is the cause of this bug.

I used this shell function for testing:
```sh
random-color-f () {
node -e "var randomColor = require('randomcolor'); // import the script
var color = randomColor({count: 1}); // a hex code for an attractive color
console.log(JSON.stringify(color))" | jq -re '.[]'
}
```

**Old report where I thought setting `hue` to `random` is the problem:**

Here is a recording (In which I use the CLI of #126):

I have tested this multiple times, it always uses red. Possibly related to https://github.com/davidmerfield/randomColor/issues/114.
