Highchart won't show all the stocks in different color

I just finished my (StockChartApp)[https://yasser-chartstocks.herokuapp.com/].

But HighChart is behaving weirdly.

When I add a new stock, the stock gets updated but it gets the color of a previous stock.

But when I refresh all stocks have different colors.

Any guesses why that could be happening ?

Here is the relevant HighChart code

github.com

yasserhussain1110/ChartStocksApp/blob/master/client/lib/StockChartLib.js

import {Theme, Options} from './StockChartConfig';
import Highcharts from 'highcharts/highstock';
import randomColor from 'randomcolor';
Highcharts.setOptions(Theme);

const updateStockChart = (allSeriesOptions) => {
  allSeriesOptions.forEach(s => {
    s.color = randomColor({luminosity: 'dark'});
  });
  Options.series = allSeriesOptions;
  Highcharts.stockChart('chart', Options);
};


export default updateStockChart;
