    it('should compare the homepage', () => {
        cy.visit("/");

You will need to alter your image difference threshold. Right now it is set to 0.001. You'll need to either set a new base reference image or change the option to allow for more difference before failing the test.

In your <rootDir>/cypress/support/commands.js, you can alter the option

addMatchImageSnapshotCommand({
  // alter to your choosing
  failureThreshold: 0.05, // threshold for entire image
});
