[BUG] Strange issue with chartjs-color

Expected Behavior

Ideally, it would be great to fallback to a value, and catch this as an exception rather throw Error.

Current Behavior

Better handling of Error, when this error occurs, the chart disappears. Main issue with this bug is a string value to “center” is causing an error to be thrown.

Possible Solution

Add validation to if statement to match only valid Rgba values. chartjs-color/index.js (line 25-35)

if (typeof obj === 'string') {
    vals = string.getRgba(obj);
if (vals) {
    this.setValues('rgb', vals);
} else if (vals = string.getHsla(obj)) {
    this.setValues('hsl', vals);
} else if (vals = string.getHwb(obj)) {
    this.setValues('hwb', vals);
} else {
    throw new Error('Unable to parse color from string "' + obj + '"');
}

Steps to Reproduce (for bugs)

This bug is rather difficult to produce, occurs occasionally.
