Idea for background of cookbook

Despite the initial ideology that Vegan food is 'boring' and 'all natural' (even that it isn't) I want to keep the theme of it being somewhat clean eating. I feel a lot of vegan cookbook selling points are based around health more than anything else - so I would like to portray that ideal despite the contents actually including (essentially) shitty fast, junky food. Therefore, for the background of the cookbook, the plan is to take the colour from a Katie Scott illustration because her backgrounds are a neutral, perfect off white therefore insinuating a neutral/natural feel to everybody who's looking at the actual book.
