Course Introduction：The color selection can be achieved through the screen color picker, which is easy to operate and practical. Common tools include Windows' "magnifying glass", ColorPicker, macOS's "digital colorimeter", and cross-platform online tools. When using it, press the shortcut key (such as Ctrl/Cmd C) to activate the straw tool, and click on the target area to copy the color value. Techniques include observing color changes and selecting the closest color, sampling multiple points to average, and using magnification preview to improve accuracy. Application scenarios cover UI design, CSS style, brand color extraction, etc., but attention should be paid to the impact of screen brightness and device differences on color accuracy. It is recommended to take colors in standard display mode and combine multiple devices or professional color calibration tools to ensure consistency.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
