Apple's first logo, designed by Ron Wayne, depicts Sir Isaac Newton sitting under an apple tree. It was almost immediately replaced by Rob Janoff's "rainbow Apple", the now-familiar rainbow-colored silhouette of an apple with a bite taken out of it. Janoff presented Jobs with several different monochromatic themes for the "bitten" logo, and Jobs immediately took a liking to it. However, Jobs insisted that the logo be colorized to humanize the company.[216][217] The logo was designed with a bite so that it would not be confused with a cherry.[218] The colored stripes were conceived to make the logo more accessible, and to represent the fact the Apple II could generate graphics in color.[218] This logo is often erroneously referred to as a tribute to Alan Turing, with the bite mark a reference to his method of suicide.[219][220] Both Janoff and Apple deny any homage to Turing in the design of the logo.[218][221]
