Anyone know what wordpress theme these two sites are using???

thewirecutter dot com

outdoorgearlab dot com

I want to make my first site very similar setup to these (its going to be a large site - not micro-niche) - wanting to know what theme it is so I can see how they get their home pages and category pages like that as that is EXACTLY what i want

Custom themes

any suggestions on what wordpress themes would be closest to this?

I like the colormag theme.....just wondering which theme to use as I want one thats responsive and fast loading, but I like to be able to have my categories all at the top bar under the header, but then also show all the categories on the homepage when scrolling down using featured images like the wirecutter does
