TextChatMessageProperties

Overrides TextChatMessage properties when returned by callbacks defined in TextChatService.OnIncomingMessage or TextChannel.OnIncomingMessage. This can be used to customize the appearance of a message with rich text tags.

local TextChatService = game:GetService("TextChatService")

TextChatService.OnIncomingMessage = function(message: TextChatMessage)
  -- Derive chat message properties
  local properties = TextChatService.ChatWindowConfiguration:DeriveNewMessageProperties()

  -- Change color of message
  properties.TextColor3 = Color3.fromRGB(255, 121, 121)

	-- Set chat window message properties
  message.ChatWindowMessageProperties = properties

  return properties
end
