You’re gonna have to use TextChatService.OnIncomingMessage (might only work for the new TextChatSystem not Legacy)

How do I change System Text's Color on the new TextChatService?

For those who are reading this in the future, you can use TextChannel.OnIncomingMessage or TextChatService.OnIncomingMessage to handle this in the future. The two properties are similar except TextChannel’s will only run on messages that go through the channel and TextChatService’s will run on all messages. For example, this snippet will change the message color of all messages that would display in the default RBXSystem channel. TextChatService.OnIncomingMessage = function(textChatMessage) …

To add onto what @Doomcolp mentioned

local TextChatService = game:GetService("TextChatService")

TextChatService.OnIncomingMessage = function(textChatMessage)
	if not textChatMessage.TextChannel then return nil end
	
	if string.sub(textChatMessage.Text, 1, 3) == "/me" then
		local overrideProperties = Instance.new("TextChatMessageProperties")
		overrideProperties.Text = string.format("<font color='#555555'>%s</font>", textChatMessage.Text)
		return overrideProperties
	end
	
	return nil
end
