I don’t know if its possible, but I’m trying to change a TextColor3 form a surfaceGUI.Textlabel (Textlabel = TrainingRoomTextChange) with a tween, but I get this error: Unable to cast value to Object

local TweeningInfoColorChange1= TweenInfo.new(
	.3,
	Enum.EasingStyle.Quad,
	Enum.EasingDirection.Out
)

local BlueToRedColorChange2 = {
	Color = Color3.new(255,0,0)
}
local RedToBlueColorChange2 = {
	TextColor3 = Color3.new(0, 170, 255)
}



local function COLORCHANGEBtoR()
	for _, v in pairs(workspace:GetDescendants()) do
		if v:FindFirstChild("TrainingRoomTextChange") then
			local ColorChange1BlueToRed = TweenService:Create(v.TrainingRoomTextChange.TextColor3,TweeningInfoColorChange1,BlueToRedColorChange2)
			local ColorChange1RedToBlue = TweenService:Create(v.TrainingRoomTextChange.TextColor3,TweeningInfoColorChange1,RedToBlueColorChange2)
			ColorChange1BlueToRed:Play()
		end
	end
end

local function COLORCHANGERtoB()
	for _, v in pairs(workspace:GetDescendants()) do
		if v:FindFirstChild("TrainingRoomTextChange")  then
			local ColorChange1BlueToRed = TweenService:Create(v.TrainingRoomTextChange.TextColor3,TweeningInfoColorChange1,BlueToRedColorChange2)
			local ColorChange1RedToBlue = TweenService:Create(v.TrainingRoomTextChange.TextColor3,TweeningInfoColorChange1,RedToBlueColorChange2)
			ColorChange1RedToBlue:Play()
		end
	end
end

When I got that right your mistake is to use the color value of the instance rather the instance itself. The tweens should be like that with a instance as the first argument:

local ColorChange1BlueToRed = TweenService:Create(v.TrainingRoomTextChange,TweeningInfoColorChange1,BlueToRedColorChange2)
