I don’t remember when I first stumbled upon Daniel Crisman’s BASH script on Colours () but kept returning to it. I created a short PowerShell script, Out-Colors.ps1, to validate the output of PowerShell color commands and to see how they aligned with the Solarized specification.

Trying to see if I was getting the Solarized color scheme colors correct, I started writing test scripts to help me see the results. PowerShell used a Dark Blue background instead of DOS’s Black, but little else. Although the Command Prompt had support for different colors, making changes sometimes had unexpected and adverse results. It was about this time that I was introduced to the cmd-colors-solarized ( permlink) project. While I had used a Solarized color scheme on my terminal for a while, Windows lacked any easy way to do this. Almost a year later, Wind(Anniversary Update) introduced the first significant version of the Console’s new VT engine and was quickly followed with the 1703 (Creators Update) release, which contained much richer support for a wider range of VT sequences. Even the change from DOS to NT, Microsoft’s compatibility story meant that introducing minor changes to how Command Prompt worked could result in significant breakdown in enterprise settings.įinally, with Wind(November Update) Microsoft introduced rudimentary ANSI Escape Sequence support. While Linux Terminal Emulators widely embraced the richness that ANSI Escape Sequences provided, Windows Command Prompts did nothing to change this.

DOS did not have this support by default and because the driver used BIOS to change the color output to a screen, it was slow and used infrequently. ANSI Escape Sequences were adopted as a standardized way to control video terminal I/O including color building from the terminal design which has a linage going back to the teletype. ANSI.SYS was a driver loaded in CONFIG.SYS when DOS was initialized on boot, which allowed the console to process ANSI Escape Sequences. While the Windows Command Prompt has supported color since it was DOS, using the color command, MS-DOS 2.0 brought the world ANSI.SYS.
