Unifying KiTTY Session Colors in Windows Registry

Forcing a monochromatic mode while maintaining distinct background colors for environments (DEV, TEST, PROD) eliminates the unreadability of the built-in ANSI palette in terminal editors.

Environment Preparation and Backup

. Perform a full export of the HKEY_CURRENT_USER\Software\9bis.com\KiTTY\Sessions branch to a base .reg file. . Create a copy of this file to serve as the working file. . Delete the Sessions branch from the Windows registry.

Processing the Working .reg File

Step 1: Removing Existing Video Attributes

Find: [literal] ^"(Colour[0-9]+|AnsiColour|Xterm256Colour)"=.*\r?\n

Replace: (leave blank)

Step 2: Injecting the Monochromatic Profile

Find: [literal] ^([HKEY_CURRENT_USER\Software\9bis.com\KiTTY\Sessions\.*])

Replace: [literal] $1\r\n"AnsiColour"=dword:00000000\r\n"Colour0"=“255,255,255”\r\n"Colour1"=“255,255,255”\r\n"Colour18"=“0,0,0”\r\n"Colour19"=“255,255,255”

Step 3: Assigning Background (Colour2) by Name Patterns

DEV Rule (suffix ’d’):

Find: [literal] ^([HKEY_CURRENT_USER\Software\9bis.com\KiTTY\Sessions\[^]]*d(?:%2E[^]]+|.[^]]+)?])

Replace: [literal] $1\r\n"Colour2"=“73,111,55”

TEST Rule (suffix ’t’):

Find: [literal] ^([HKEY_CURRENT_USER\Software\9bis.com\KiTTY\Sessions\[^]]*t(?:%2E[^]]+|.[^]]+)?])

Replace: [literal] $1\r\n"Colour2"=“32,128,145”

PROD Rule (suffix ‘p’):

Find: [literal] ^([HKEY_CURRENT_USER\Software\9bis.com\KiTTY\Sessions\[^]]*p(?:%2E[^]]+|.[^]]+)?])

Replace: [literal] $1\r\n"Colour2"=“142,56,32”

PROD Rule (nodes containing ‘-plx-’):

Find: [literal] ^([HKEY_CURRENT_USER\Software\9bis.com\KiTTY\Sessions\[^]]-plx-[^]]])

Replace: [literal] $1\r\n"Colour2"=“142,56,32”
