How do I make a part's color become the color of a backgroundcolor3 in a textbutton?

So basically i am trying to make this GUI where you can insert parts, change its color and position. But I keep getting this error that says, "Color is not a valid member of textbutton." Anyways here are my 2 scripts

-- local script

local buildingGUI = script.Parent
local BuildingFrame = buildingGUI:WaitForChild("BuildingFrame")

local CreatePartButton = BuildingFrame.CreatePartButton
local ColoringFrame = buildingGUI.ColoringFrame

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local BuildObjects = ReplicatedStorage:WaitForChild("BuildObjects")

local canMovePart = false

local part = BuildObjects.Part

local mouse = game:GetService("Players").LocalPlayer:GetMouse()

local BuildEvent = ReplicatedStorage.RemoteEvents.BuildEvent


CreatePartButton.MouseButton1Click:Connect(function()
local clonedPart = part:Clone()
    clonedPart.Parent = game.Workspace
    clonedPart.Transparency = 0.7
    clonedPart.Position = mouse.Hit.p

    ColoringFrame.Visible = true

    for i, v in pairs(ColoringFrame:GetChildren()) do
        if v:IsA("TextButton") then
            v.MouseButton1Click:Connect(function()
                local selectedColor = v
                local backGroundColor = v.BackgroundColor3
                clonedPart.Parent = game.Workspace
                clonedPart.Position = mouse.Hit.p
                mouse.Move:Connect(function()
                    if canMovePart == false then

                    clonedPart.Position = mouse.Hit.p
                        mouse.Button1Down:Connect(function()
                            local finalPartPosition = mouse.Hit.p
                            BuildEvent:FireServer(backGroundColor,selectedColor,clonedPart,finalPartPosition)
                            canMovePart = false
                        end)
                        end
                end)
                end)
            end
        end

    end)

-- server script


local ReplicatedStorage = game:GetService("ReplicatedStorage")

local RemoteEvents = ReplicatedStorage.RemoteEvents
local buildEvent = RemoteEvents:WaitForChild("BuildEvent")

buildEvent.OnServerEvent:Connect(function(backGroundColor,selectedColor,clonedPart,finalPartPosition)
    clonedPart.Color = Color3.new(backGroundColor)
    clonedPart.Position = finalPartPosition
    clonedPart.Transparency = 0

    clonedPart.Parent = game.Workspace
end)
