Message text not saying part BrickColor?

The line of code that says "msg.Text = ("The part color isn't bright blue it is" .. part.BrickColor)" won't work, the output says "attempt to concatenate field 'BrickColor' (a userdata value)" what does that mean help!?

local part = workspace.Part 
part.Touched:connect(function(touch) 
local msg = Instance.new("Message", workspace) 
part.BrickColor = BrickColor.Random() 
if part.BrickColor == BrickColor.new("Bright blue") then 
msg.Text = ("The part color is now bright blue") 
else 
msg.Text = ("The part color isn't bright blue it is" .. part.BrickColor) 
end 
end)
