How to remove the Greyish outline of multicolumn on home page? - Dawn theme

[BraxtonEcom]

I would like to remove the greyish outline around both of the below images from the multicolumn section on the homepage. I would like it so that it is just the same plain background all around #FAFAFA.

Theme: Dawn

Any advice is really appreciated
