[javascript] reactjs - how to set inline style of backgroundcolor?

I want to set the style properties of some elements but I don't have the syntax correct. Can anyone suggest where I am wrong?

import React from 'react';
import debug from 'debug'

const log = debug('app:component:Header');

var bgColors = { "Default": "#81b71a",
                    "Blue": "#00B1E1",
                    "Cyan": "#37BC9B",
                    "Green": "#8CC152",
                    "Red": "#E9573F",
                    "Yellow": "#F6BB42",
};

export default class SideBar extends React.Component {

  constructor(props) {
    super(props);

  }


  render() {

    return (


    <a style="{{backgroundColor: {bgColors.Default}}}" >default</a>
    <a style="{{backgroundColor: {bgColors.Blue}}}" >blue</a>
    <a style="{{backgroundColor: {bgColors.Cyan}}}" >cyan</a>
    <a style="{{backgroundColor: {bgColors.Green}}}" >green</a>
    <a style="{{backgroundColor: {bgColors.Red}}}"  >red</a>
    <a style="{{backgroundColor: {bgColors.Yellow}}}" >yellow</a>
           );
  }

}

UPDATE: for anyone looking at this please see comments this is not working code.

If you want more than one style this is the correct full answer. This is div with class and style:

<div className="class-example" style={{width: '300px', height: '150px'}}></div>

Your quotes are in the wrong spot. Here's a simple example:

<div style={{backgroundColor: "#FF0000"}}>red</div>
