I'm building a suggestion engine web application, it will be very minimal .
The users will need to fill a form to get the result, the form has around 7 to 8 inputs that must be filled . I already figure out how to keep the input UX smooth .
However I don't know which background type should I use : Image, Color , Simple Colored Patterns or just white .
My web app let the user interact and use it directly,it's UX is similar to google home page, but instead of one large text input (the search bar) . I do have multiple inputs .
So how can I chose the right background ? I'm also looking at a material design UI .
