[10] The designers of the first Apple Color Emoji typeface were Raymond Sepulveda, Angela Guzman and Ollie Wagner.
[12] For example, 💃 (defined by Unicode as 'dancer' with no specified gender) is feminine on Apple and SoftBank phones[13] but was previously masculine or gender-neutral on others.
[19][20] The majority of Apple Color Emoji designs were updated with the release of iOS 10.2 in December 2016, with many appearing to be 3D-rendered.
[21] According to Apple Vice President of User Interface Design Alan Dye, emoji redesigns were due to the advent of Animoji, Memoji, and higher resolution screens.
[27][28] Emoji glyphs are stored as PNG images,[29] at several resolutions (strikes of 20, 32, 40, 48, 64, 96 and 160 pixels squared) using a proprietary "sbix" table that was later standardized in OpenType version 1.8.
Several glyphs contain portions of the text of Apple's Think different advertisement ("Here's to the crazy ones..."), including 1F4CB "Clipboard" (📋), 1F4C4 "Page facing up" (📄), 1F4D1 "Bookmark Tabs" (📑), and 1F4D6 "Open book" (📖), among others.
