How to use the command 'color' (with examples)

The ‘color’ command is a command-line utility primarily used in Windows-based systems to alter the foreground and background colors of the command prompt console. By using this command, users can enhance the visual appearance of the console window, making it easier to distinguish between different types of outputs, or simply giving it a more personalized look. This can be particularly helpful for people spending prolonged periods working with the command prompt, improving both aesthetics and readability.

Use case 1: Set the console colors to the default values

Code:

color

Motivation: Over time, users may adjust their console’s appearance to non-default settings for clarity, preference, or experimentation. However, there may come a time when a return to the original settings is necessary—perhaps for the sake of uniformity across systems, after experimenting with various color combinations, or when a user finds the customized colors are leading to less-than-ideal contrast and readability. Returning to default values can help ensure the command prompt looks and feels familiar, removing any distractions caused by unsuitable colors.

Explanation:

• The color command without any arguments resets the console to its default colors. This is akin to a ‘reset’ button, undoing any changes previously made to the console colors.

Example output: Upon entering the command, you might no longer see a change in color, but you return to the customary console colors associated with your system or predefined settings established for new command prompt windows—often a default white text on a black background (or vice versa).

Use case 2: List available color values and detailed information

Code:

color /?

Motivation: Whether you’re new to customizing the appearance of your command prompt or a seasoned user who occasionally forgets specific codes, knowing the options at your disposal is crucial. The command prompt offers a variety of colors represented by hexadecimal codes, which might not be self-explanatory. Understanding what each color represents allows for intentional and informed customization, providing a quick reference or refresher on the available choices.

Explanation:

• The / symbol indicates an option or switch in command line syntax.
• The ? is a common convention for requesting help or documentation related to that command. Together, /? instructs the utility to display help information, including a list of acceptable color values.

Example output: After executing the command, you will see a list of hexadecimal numbers and their corresponding colors, giving you a clear reference guide for setting the console’s appearance. This might look something like:

Digit   Color
0       Black
1       Blue
2       Green
3       Aqua
4       Red
5       Purple
6       Yellow
7       White
8       Gray
9       Light Blue
A       Light Green
B       Light Aqua
C       Light Red
D       Light Purple
E       Light Yellow
F       Bright White

Use case 3: Set the console foreground and background to a specific color using hexadecimal numbers

Code:

color 0a

Motivation: Customization is a powerful tool for users who frequently interact with command line interfaces. By setting specific colors, users can create an environment that is soothing to their eyes, improves focus, or simply matches their aesthetic preferences. This particular example sets the background to black and the text to bright green, a classic color combination that is often associated with old-school computer terminals and seen as easy on the eyes.

Explanation:

• Each color setting requires two hexadecimal codes: one for the background and one for the foreground (text).
• The first character ‘0’ sets the background color to black.
• The second character ‘a’ (or ‘A’) sets the foreground color to light green. These codes correspond to the hexadecimal values described in the previous use case.

Example output: Upon executing this command, the command prompt window’s background will turn black, and the text will appear in a bright green color, producing a visually distinct interface reminiscent of early computing terminals.

Conclusion:

The ‘color’ command provides a simple yet effective way to customize the aesthetic of your Windows command prompt environment. Whether you are resetting to the default look, exploring the array of available colors for inspiration, or applying specific combinations for a unique setup, understanding the application and structure of the ‘color’ command can enhance your command line experience in meaningful ways. With this knowledge, users are empowered to create a console environment better suited to their personal preferences and work requirements.
