This line of code is making each candlestick a different color in my PaintBar study. (Resaving changes the color palette.)

PlotPB(High, Low, Open, Close, "", elsystem.drawing.color.FromArgb(255,255,255,255) );

Any idea why? Shouldn't it just make them all white?

swingbatter,

as far as I am aware legacy plots are not designed to use Color objects, they are intended for the standard or custom foreground and background color to a Forms control or DrawingObject (while plots are not a DrawingObject). Plots expect legacy colors, one of the 16 named colors (like Red or Blue etc.) or RGB/ARGB values.
"elsystem.drawing.color.FromArgb(255,255,255,255)" is not an integer or double and what value Tradestation uses
when you use it with legacy plots might be a question to ask the developers directly. The reason why you are seeing different
colors for every bar is likely due to the fact that you create a new instance of the object on every code calculation.
If you would create the color once only and then use that going forward, you should see the same color for all bars (although likely
not white).

For your code snippet the better approach would be using something along the lines of:

Variables:
int plotColor ( ARGB( 255, 255, 255, 255) );

PlotPB(High, Low, Open, Close, "", plotColor );
