This logo is a reinterpretation based on the classic APL [[apple]] with the leaf styled as a filled [[Del]] which symbolises [[function]] definition and has been used in application icons for [[APL+]] and [[APLX]]. The green colour comes from [[IBM]]'s modern '''Carbon''' design to honour IBM's role APL's history. The apple is subdivided into a rectangular pattern which is supposed to invoke a [[matrix]] and the middle row in turn holds three 4-row, 3-column [[Boolean]] matrices to spell out "APL" as bitmaps. This matrix of matrices hints at APL's multi-dimensional [[nested array]]s. The logo exists in various variations, and each comes has a version for light backgrounds and one for dark backgrounds. | This logo is a reinterpretation based on the classic APL [[apple]] with the leaf styled as a filled [[Del]] which symbolises [[function]] definition and has been used in application icons for [[APL+]] and [[APLX]].
