Bug description

If a player has the essentials.chat.rgb permission, but not any other color permissions such as essentials.chat.color, the RGB code will be stripped from the message. This seems to be due to expanding color codes into the vanilla §x§r§r§g§g§b§b format, then stripping the color codes the player does not have access to.

This screenshot is the result of sending "&#ff0000test" with the following essentials.chat.<suffix> permissions, top to bottom:

1. rgb
2. rgb, color
3. rgb, white
4. rgb, black
5. rgb, black, white

Messages 1, 3, and 4 display as "§xtest" in console.

Also happens in latest stable (2.19.6).

Steps to reproduce

1. Give yourself the essentials.chat.rgb permission, but NOT any other chat color permissions
2. Type "&#ff0000test"

Expected behaviour

Should display "test" in bright red

Actual behaviour

Displays "test" in white
