@maddovr This is because there is the background: #fff style applied to Menu component. I will fix that soon. Till then you can apply customStyle to the Menu

import { css } from 'emotion';

/* ... */

const menuCustomStyle = css`
  background: #<color-you-need>
`;

const IndexPage = props => {
  /* ... */

  return <Layout customStyle={layoutCustomStyle}>
...
<Menu customStyle={menuCustomStyle}>...</Menu>
</Layout>;
};

That should fix the issue.
