How to change a Hint's Color Value?

I took Pictures as a reference to my question

What I am trying to do is set a Hint for this game but make the colors glow neon and black so it pops out better.

This is the current hint: Edit: it didn't go through because of a bugup in my Bandicam's video/picture capture. Note: The hint I was trying to make is just the default black and white hint.

This is my desired hint: Imgur link to Hint

The thing is, I'm not sure of the way. I know that there has something to do with the Color of it, but I can't tell what to edit, so I pieced it out.

while true do
local h = Instance.new("Hint")
h.Parent = game.Workspace
h.Text = "Welcome to Paintball Warfare, created by JustGimmeDaBux" -- The message I'm talking about.
wait(8) --I know wait(8) is a small wait time but it will be updated in the future.
h.Text = "Mapmakers will soon be needed! Start working on maps!" -- Not yet ;)
wait(8)
h.Text = "The expected release date is 02/01/2015"
wait(8)
h.Text = "Have fun on Paintball Warfare!"
end

Once I rewrote it and dillydallied with some colors, this is what I got:

while true do
local h = Instance.new("Hint")
h.Parent = game.Workspace
h.Text = "Welcome to Paintball Warfare, created by JustGimmeDaBux" -- I excluded the green text.
local.Color(Lime green, Really black) 
wait(8)
h.Text = "Mapmakers will soon be needed! Start working on maps!"
local.Color(Lime green, Really black) 
wait(8)
h.Text = "The expected release date is 02/01/2015"
local.Color(Lime green, Really black) 
wait(8)
h.Text = "Have fun on Paintball Warfare!"
local.Color(Lime green, Really black) 
end
	end --My friend told me that when you add in the local.Color script you need to end it separately, but I doubt it.

All the help I can get would be awesome. Thanks

You all rock. Have a nice day SH!

Like messor said, this is impossible. Although i was so surprised that I went to test it. But you can make what you want with a textlabel. I can also show you how to change a single player's ambient if you want.

To add on to notsopwnedg's code:

--Please note that this will not work if you have Filtering enabled

local Screen = Instance.new("ScreenGui")
local Label = Instance.new("TextLabel",Screen)
Label.Size = UDim2.new(1,0,.04,0) --Change Size to your liking,
Label.TextColor3 = Color3.new(0,1,0) --Lime Green
Label.BackgroundColor3 = BrickColor.Black().Color
Label.BackgroundTransparency = .5
Screen.Name = "Hint"
Label.Text = "Welcome!"

--Give the Gui to who you want to.
Game.Players.PlayerAdded:connect(function(Player)
Player.CharacterAdded:connect(function(char)
wait()
Screen:Clone().Parent = Player:WaitForChild('PlayerGui');
end)

No no no... what you took a picture of is called a Gui--> TextLabel there is no way in Rbx.Lua to change color of a 'Hint' or a 'Message'. There two different things.
