                                                   ChartSmoothLine is immune to UpdateColor. Design choice or bug?

I might have missed it, but I didn't see it documented anywhere. And it doesn't logically make sense.
It appears in my testing that ChartSmoothLine always reacts to UpdateColor, first argument true or not.
Is this a bug? Or am I overlooking some documentation?

It was with some frustration that I spent time debugging why this simple plot wasn't coloring correctly.
The ema5 line was always purple, which made absolutely no sense.
Plot (ema13,"EMA13",ColorBlue,ChartSmoothLine,StyleWidth3);
Plot (ema5,"EMA5",ColorLightBlue,ChartSmoothLine,StyleWidth3);
UpdateColor (ema5<ema13,colorPurple);

After I replaced ChartSmoothLine with ChartLine, the script plotted as expected.
Ema5 was light blue above Ema13 and switched to purple below Ema13:
Plot (ema13,"EMA13",ColorBlue,ChartLine,StyleWidth3);
Plot (ema5,"EMA5",ColorLightBlue,ChartLine,StyleWidth3);
UpdateColor (ema5<ema13,colorPurple);

Thanks as always,
Josh McCormick

Trading financial instruments, including foreign exchange on margin, carries a high level of risk and is not suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to invest in financial instruments or foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with trading and seek advice from an independent financial advisor if you have any doubts.
