Data Brushing Callback; Assign (Keep) Brush Color

Hi, I have created a callback function for data brushing (called with 'ActionPostCallback'). When I use the brush, I always set the color to Magenta ('Color',[1 0 1]) so that the brushed points are visible (some of my graphs contain red points, the default brush color).

However, when I the callback is used, the brush color is reset to the default red. I have tried setting the color ('MarkerEdgeColor') of the brush handle to magenta in the callback, but this results in an error (Below this paragraph). I think the error results from my trying to modify the brush handle inside of the callback for that handle.

Callback Error:

Warning: An error occurred during the mode callback.

My question is : Is there anyway for me to maintain my choice of brush color, or to assign a brush color inside of the callback? Thanks for the help!

Code For activating brushing:

   hBrush = brush(figHandle);
    set( hBrush,'ActionPostCallback', @(ohf, s) brushDataCallback, 'enable', 'on', 'Color', [1 0 1] )

Code in Callback to set color to Magenta

% Update All figures with Brushed Data
figHandles = findall(0,'Type','figure');
for ii = 1:length(figHandles)
    brDataFig = findobj(figHandles(ii),'-property','BrushData');
    set(brDataFig,'BrushData',brDataInd)
    hb = findall(figHandles(ii),'Tag','Brushing');
    set(hb,'MarkerEdgeColor',[1 0 1]);
    % NOTE: I have also tried properties 'MarkerFaceColor' and 'Color', neither worked
end
