Supported Color Formats

The chat and sign nodes above unlock the same set of formats. Anything a player types that they lack the permission for is stripped rather than sent through.

Format	Syntax	Example
Legacy codes	& followed by a code	&aGreen, &lBold
Hex	#RRGGBB	#ff8800Orange
Hex, braced	{#RRGGBB}	{#ff8800}Orange
Hex, Spigot form	&x&R&R&G&G&B&B	&x&f&f&8&8&0&0Orange
Solid	<SOLID:RRGGBB> or #{RRGGBB}	<SOLID:ff8800>Orange
Gradient	<GRADIENT:RRGGBB>text</GRADIENT:RRGGBB>	<GRADIENT:ff0000>Sunset</GRADIENT:0000ff>
Rainbow	<RAINBOW{saturation}>text</RAINBOW>	<RAINBOW80>Colorful</RAINBOW>

Gradient and rainbow interpolate across the enclosed text, so they need both an opening and a closing tag. The rainbow saturation is a number from 1 to 100.

These formats are also accepted anywhere messages.yml takes text, independently of these permissions -- the nodes govern what players may type, not what you may configure.
