Custom Emoji To Set Within An Existing Font

I was approached by Page Two Books to create a custom set of emojis for a book layout they were typesetting. The author had employed ample use of emojis in their manuscript and we needed one colour emojis that would blend in with the chosen text typeface, Lyon by Kai Bernau. 

emojis: blast, smiling pile of poo, message, winking face, smirk, smile, eye-roll, none, angry, brain explode, light bulb, typing

The emojis were sized and spaced to fit well in paragraphs of text. They were provided in a font format to make typesetting the book much more efficient because the emojis were already spaced vertically and horizontally to work within the text. All the designer needed to do when they needed an emoji was to change the font and maybe kern a bit if the spacing felt off.

When designing the emojis, we borrowed from the shapes found in the terminals of the typeface and matched the line thickness to the uppercase. We positioned them in centered vertically on the capitals and made them slightly larger. They needed to stand out as something different to the text but create a sense of harmony with the text at the same time.
