How can I make this line of code have a BrickColor randomized?

if 2+2==5 or 2*2.5==5 then
    for i = 1,10 do
        x=Instance.new("Part",Workspace)
        x.Name = "Base"
        x.BrickColor =  "Bright Orange" --Problem here... so far.
        x.Size = Vector3.new(5,5,5)
        x.Position = Vector3.new(math.random(100),math.random(100),math.random(100))
        x.Transparency = math.random()
    end
end
