  The PuTTY iconography uses a stylized computer terminal displaying a kawaii face, representing the software's friendly nature despite its powerful functionality. The different icons distinguish PuTTY's various tools through color and added imagery. For instance, PSCP (secure copy) features a document with a downward arrow, while PSFTP (secure file transfer protocol) shows a pair of opposing arrows, symbolizing bi-directional transfer. The colors roughly correspond to the traffic light system, with green for connection tools (PuTTY, Plink), amber for file transfer tools (PSCP, PSFTP), and red for key generation (PuTTYgen). The overall design prioritizes simplicity and memorability over strict adherence to real-world terminal appearances or symbolic representation.

  Simon Tatham, the author of PuTTY, provides a comprehensive explanation of the design choices behind the suite's various application icons. He begins by acknowledging the common confusion surrounding the seemingly arbitrary assignment of icons to specific tools. He then details the deliberate thought process that went into crafting each icon, emphasizing a systematic approach rooted in visual symbolism and the desire for clear differentiation.

  The core concept revolves around representing each tool's function through metaphorical imagery related to its purpose. For example, PuTTY itself, being a terminal emulator, is symbolized by a computer terminal window, albeit an abstract and simplified one to accommodate the small icon size. This window motif is then modified and augmented to represent the related but distinct functions of the other tools. PuTTYgen, used for key generation, adds a golden key to the basic window icon, signifying its role in creating cryptographic keys. Pageant, the key agent, features a tiara superimposed on the window, symbolizing its function as a "king" or manager of keys. PSCP, the secure copy tool, incorporates a document with a prominent downward-pointing arrow, visually depicting the action of copying files to a destination. PSFTP, the secure file transfer tool, uses a similar document icon but with upward and downward arrows, representing bidirectional file transfer. PLink, the command-line connection tool, displays a lightning bolt over the window, symbolizing its fast and direct connection capability.

  Tatham further elaborates on the practical considerations that influenced the icon design. He highlights the constraints imposed by limited resolution and the need for icons to be readily distinguishable, even at small sizes. This led to the adoption of simple, bold shapes and contrasting colors. He specifically addresses the choice of a yellow or gold color for elements representing security and encryption, aiming for a clear visual cue associated with these crucial functions. He also explains the deliberate use of distinct, easily identifiable shapes for each icon to prevent confusion among users.

  Finally, Tatham acknowledges the subjective nature of aesthetics and the potential for differing interpretations of the iconography. While acknowledging that the chosen symbolism might not be universally intuitive, he defends the internal consistency and logical basis of the design decisions, emphasizing the importance of having a clear and reasoned rationale behind the visual representation of the PuTTY tool suite.
