Later forms show the palm slightly cupped upward instead, but all the fingers remain distinguished in detailed depictions through the New Kingdom. The most detailed examples of all tend to follow the Old Kingdom form. This glyph was conventionally colored red. The phonetic value of ꜥ is derived by the rebus principle from its use as the logogram for ꜥ(“arm”).
