body: I'm building a site that aggregates food delivery services in my region. I show all the companies I collected as a list of cards, where each card contains the logo of a company, company name, link to the site of the company and other information.
  
  
  I have one problem though. Some companies use white logos on a transparent background. My site's background is white, therefore those logos are invisible. Is it legal to invert the logos (make them black) without asking each company?
