What is the term used to define the look and feel of an application in Pega?

In Pega, the term that defines the look and feel of an application is referred to as "Skin." The Skin encompasses all aspects of the application's visual design, such as color schemes, fonts, button styles, and other UI elements. It essentially allows developers and designers to create a cohesive visual experience that aligns with the branding and design guidelines of the organization.

Using the concept of Skin in Pega enables teams to maintain consistency across different parts of the application and make global changes to the UI efficiently. For instance, if a company decides to rebrand and change its colors or fonts, adjustments can be made within the Skin, and those changes propagate throughout the application wherever the Skin is applied.

The other terms, while related to aspects of application design, do not specifically encapsulate the complete visual styling as comprehensively as Skin does. For example, a Theme typically refers to a pre-defined set of styles, but it doesn't cover the customizability that a Skin allows. Interface relates more to how users interact with the application rather than the visual representation. Layout refers to the structure of UI components on the screen, but again, it does not encompass the overall aesthetic qualities defined by a Skin.
