-- Make some default colour
R = 255
G = 255
B = 255
A = 255

-- This function draws the text, and the color is decided with tocolor(R, G, B, A)
function drawDX()
	dxDrawText("Tuna", 10, 10, 100, 100, tocolor(R, G, B, A), 1)
end
addEventHandler("onClientRender", root, drawDX)
-- This will make some DX text (Tuna) appear at the top left of your screen.

--Now to modify the R, G, B, and A with a command.
function editRGBA(command, red, green, blue, alpha)
	if (tonumber(red) and tonumber(green) and tonumber(blue) and tonumber(alpha)) then -- Make sure the user entered all 4 args as numbers.
		R = tonumber(red)
		G = tonumber(green)
		B = tonumber(blue)
		A = tonumber(alpha)
		-- tonumber() had to be used here else tocolor() didn't display the right color.
		outputChatBox("Color of Tuna set to the color of this text, with "..A.." alpha.", R, G, B)
	end
end
addCommandHandler("setcoloroftuna", editRGBA) -- setcoloroftuna command.
-- Example /setcoloroftuna 255 0 0 255 - for red.
