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.
