Gradient
My dad was an old school graphic designer. He started his own business in the 80s after retiring from the fire department, and spent the rest of his life designing logos, computer manuals, and how-to booklets. He loved drop shadows, outdated design software, and desktop computers. But more than anything, he loved gradients. A working artist most of his life, he was still designing things – albeit slowly – up until he was diagnosed with cancer at the age of 74. He was also a great teacher.
