const stringToColor = (str) => {
    let hash = 0;
    let color = '#';
    let defaultColor = '#333333';
    let i;
    let value;
    let strLength;

    if(!str) {
        return defaultColor;
    }

    strLength = str.length;

    for (i = 0; i < strLength; i++) {
        hash = str.charCodeAt(i) + ((hash << 5) - hash);
    }

    for (i = 0; i < 3; i++) {
        value = (hash >> (i * 8)) & 0xFF;
        color += ('00' + value.toString(16)).substr(-2);
    }

    return color;
};

export default stringToColor;
