We have completely restructured the permission system to make it more logical and easier to manage:

Permission Description
"quickchat.menucolors" Required to open the color menu (/chatcolor).
"quickchat.menucolors.all" Grants access to all colors in the menu automatically.
"quickchat.menucolors.<color>" Grants access to a specific color (e.g. quickchat.menucolors.red).
Note: Legacy permissions such as chatcolors.color.* have been replaced.
