Hidden Shading

Hi team,

I have just started building a site using your Java template and can't seem to find where to change a particular background colour on the Home page. It looks like some kind of block or row or group which is shaded a very light green. It is located behind the content above the title 'Our Difference'. I've looked everywhere to try and find this as I would like to alter the position and the colour. Please can you advise where I can access this part of the page set up.

As this is a dev site, please use IP: 103.18.109.188

Thanks
