Which version of ParaView are you using? With 4.3.1, I get the following:

<snip>

# get color transfer function/color map for 'RTData'
rTDataLUT = GetColorTransferFunction('RTData')

# get color legend/bar for rTDataLUT in view renderView1
rTDataLUTColorBar = GetScalarBar(rTDataLUT, renderView1)

# Properties modified on rTDataLUTColorBar
rTDataLUTColorBar.TitleColor = [0.0, 0.0, 0.0]
rTDataLUTColorBar.LabelColor = [0.0, 0.0, 0.0]
