Rainbow design
The second logo was designed by Rob Janoff of the Regis McKenna advertising agency and entered into use in 1977, with color stripes representing the groundbreaking color capabilities of early Apple desktop computer models. The bite was added to the shape to avoid confusing it with a cherry. According to According to McKenna, inspiration for the rainbow colors was drawn from the work of another local commercial artist, Tom Kamifuji. This version was refined by in 1990.

Simplification
The colored version remained in use until a monochrome version of the logo was adopted in 1998, with the rainbow version remaining in some use until 1999. A version based on the "Aqua" theme entered into use in 2001 with the launch of Mac OS X. A cleaner metallic version of the logo entered into use in 2007 for the introduction of the iPhone. In 2013, it was simplified back to silhouette form in the release of iOS 7, under the direction of chief creative officer Jonathan Ive. The monochrome logo once again entered corporate use in 2014.
