Why won't BrickColor on this?

I made an arm script but as i was trying to add the color to the arms i noticed that this popped up in the output

18:11:27.353 - BrickColor is not a valid member of SpecialMesh

And here is where the problem is

local LArm = Instance.new("SpecialMesh")
LArm.MeshId = "rbxasset://fonts/torso.mesh"
LArm.Name = "Left Arm"
LArm.Scale = Vector3.new(.9, 1.9, .9)
LArm.BrickColor = BrickColor.new("Pastel brown")
LArm.CanCollide = false
LArm.Parent = model
local LArmWeld = Instance.new("Weld",LArm)
LArmWeld.Part0 = larm
LArmWeld.Part1 = LArm

The thing is that i have Re-written other first person arm scripts where i use the bevel mesh instead of the brick and then i change the BrickColor to Pastel Brown and it works. But for some reason it doesn't want to work with this one. Can someone please help me?

Oh and also This is a piece of code from a free model that i quickly fixed up to use a special mesh.

local mesh1 = Instance.new("SpecialMesh")
mesh1.MeshId = "rbxasset://fonts/torso.mesh"
mesh1.Scale = Vector3.new(.9,.9,.9)
mesh1.Parent = falsearm1
local armweld1 = Instance.new("Weld")
falsearm1.BrickColor = BrickColor.new("Nougat")
falsearm1.Parent = Tool
armweld1.Parent = falsearm1
armweld1.Part0 = falsearm1
armweld1.Part1 = arms[1]
falsearm2 = arms[2]:clone()

Using this script actually changes the color of the SpecialMesh. Is there a reason why this works and mine doesn't?
