Paper has been used since eons. The history of paper dates back thousands of years and it has been one of the most important tools for the development and evolution of mankind! Thus when computers came in, the dependence on paper reduced drastically. However, people still loved the texture and look of paper and so paper backgrounds became famous over time and are now in vogue!
Paper has a unique texture with its slight creases, porous membranes and flexibility. Such a background actually feels soothing and calming to look at while looking at a digital monitor or screen. Paper gives a raw and natural aesthetic that is only unique to itself and seeing text on it on a monitor brings people closer to reality through a digital screen.
The great part about paper backgrounds are the large numbers of shades that can be used on it. From pure white to space grey, off white to dirty yellow, paper can even be coloured and so can the paper backgrounds!
So a soothing, calming and reassuring texture like paper on a digital monitor or screen works as a great way to even read large amounts of text on a screen. With the rise of e-books and other online reading sites, a paper background is the best way to avoid strain to the eye and bring people an experience of reading from an actual paper based book!
