Default color option seems to have a "one off" issue.

Sorry I know you're probably sick of me...

For example: In order to apply colors properly to a two series chart you need to add three strings in the defaultColors array.

      <Chart
        options={{
          defaultColors: ["#4c26c9", "#f44336"],          // doesnt work
          // defaultColors: ['#4c26c9', '#f44336', ""],   // works
          data: data,
          primaryAxis,
          secondaryAxes
        }}
      />
