lightblue

LightBlue is a pale tint of blue that sits between blue and cyan on the color spectrum. In digital color systems, LightBlue is a named CSS color defined by the hex code #ADD8E6 and an RGB value of 173, 216, 230. It is commonly used in web design and UI to convey a calm, fresh, and approachable appearance. As a color name, LightBlue appears in the X11/CSS color set and is widely referenced in design documentation and palettes.

In addition to its role as a color, LightBlue refers to software tools related to Bluetooth Low Energy (BLE). LightBlue is the name of a BLE development tool and companion app developed by Punch Through. It provides features for scanning nearby BLE peripherals, connecting to devices, and inspecting or testing their services and characteristics. The tool is used by developers to prototype, debug, and verify BLE communications and is available on supported platforms such as iOS and macOS. The existence of LightBlue in both color references and BLE tooling illustrates how the same term can have distinct meanings in design and technology contexts.

Overall, LightBlue can denote a specific light-blue color used in design or a BLE development utility, depending on the context. Each usage serves different audiences—visual designers seeking a soft blue tone, and developers working with Bluetooth Low Energy devices.
