Touchpoint theme – edit .css / change background

Hi

I am using the touch point theme – on http://www.ranagazoo.co.uk and I am simply trying to edit the background colour of the first page.

For the life of me I cannot find where it is in the .less files.

From what I understand there is no .css to edit but the following directory

wp-content/themes/dimsemenov-Touchfolio-c481e2d/css-

I can do it when I ‘inspect elements’ in developer mode in Chrome.

If anyone can help please let me know. Also – any idea how this guy did this to his site? It’s pretty amazing: http://www.caligabimba.com/
