Git is a distributed version control system DVCS designed for efficient source code management, suitable for both small and large projects. It allows multiple developers to work on a project simultaneously without overwriting changes, supporting collaborative work, continuous integration, and deployment. This Git and GitHub tutorial is designed for beginners to learn fundamentals and advanced concepts, including branching, pushing, merging conflicts, and essential Git commands. Prerequisites include familiarity with the command line interface CLI, a text editor, and basic programming concepts. Git was developed by Linus Torvalds for Linux kernel development and tracks changes, manages versions, and enables collaboration among developers. It provides a complete backup of project history in a repository. GitHub is a hosting service for Git repositories, facilitating project access, collaboration, and version control. The tutorial covers topics such as Git installation, repository creation, Git Bash usage, managing branches, resolving conflicts, and working with platforms like Bitbucket and GitHub. The text is a comprehensive guide to using Git and GitHub, covering a wide range of topics. It includes instructions on working directories, using submodules, writing good commit messages, deleting local repositories, and understanding Git workflows like Git Flow versus GitHub Flow. There are sections on packfiles, garbage collection, and the differences between concepts like HEAD, working tree, and index. Installation instructions for Git across various platforms Ubuntu, macOS, Windows, Raspberry Pi, Termux, etc. are provided, along with credential setup. The guide explains essential Git commands, their usage, and advanced topics like debugging, merging, rebasing, patch operations, hooks, subtree, filtering commit history, and handling merge conflicts. It also covers managing branches, syncing forks, searching errors, and differences between various Git operations e.g., push origin vs. push origin master, merging vs. rebasing. The text provides a comprehensive guide on using Git and GitHub. It covers creating repositories, adding code of conduct, forking and cloning projects, and adding various media files to a repository. The text explains how to push projects, handle authentication issues, solve common Git problems, and manage repositories. It discusses using different IDEs like VSCode, Android Studio, and PyCharm, for Git operations, including creating branches and pull requests.

Introduction of CMY Color Model
The CMY color model is a subtractive color model that is used in printing and other color reproduction applications. CMY stands for Cyan, Magenta, and Yellow, which are the primary colors of ink used in printing. The CMY color model is based on the principle of subtractive color mixing, which involves subtracting colors from white light to create a desired color.
C(Cyan), M(Magenta) & Y(Yellow)
In the CMY color model, colors are created by subtracting different amounts of cyan, magenta, and yellow ink from a white background. When all three colors are combined at full strength, they create black. However, because the process of subtracting color can result in a loss of brightness and saturation, black ink is often added to improve the overall color quality.

To understand how the CMY color model works, it is helpful to think of it in terms of the color wheel. The primary colors of cyan, magenta, and yellow are positioned evenly around the wheel, with secondary colors such as red, green, and blue located between them. To create a specific color, ink is subtracted from white to produce the complementary color on the color wheel. 
For example, to create the color red, magenta and yellow ink are combined. The magenta ink subtracts the green portion of white light, while the yellow ink subtracts the blue portion, leaving only the red. To create the color green, cyan and yellow ink are combined, with the cyan ink subtracting the red portion of white light and the yellow ink subtracting the blue portion, leaving only green.
Advantage of CMY Color Model
One of the main advantages of the CMY color model is its ability to produce a wide range of colors using a relatively small number of inks or colorants. Unlike additive color models, such as RGB, where colors are created by combining light of different wavelengths, the CMY color model works by subtracting light of certain wavelengths from white light to create different colors. For example, when cyan ink is applied to a white surface, it absorbs red light and reflects green and blue light, creating the color cyan.
The subtractive nature of the CMY model allows it to produce a wide range of colors by combining different amounts of cyan, magenta, and yellow. By adding more of each colorant, the resulting color becomes darker, eventually approaching black when all three are combined in equal amounts. This makes the CMY model particularly useful in printing applications, where a limited number of inks must be used to produce a full range of colors.
Another advantage of the CMY color model is its compatibility with other subtractive color models, such as the Pantone Matching System (PMS) used in the printing industry. By using the CMY model as a basis, printers can accurately reproduce a wide range of PMS colors using a combination of cyan, magenta, yellow, and black inks. Overall, the CMY color model offers a cost-effective and flexible approach to color reproduction, making it a popular choice in a variety of industries, including printing, graphic design, and photography.
