Change color of numbers that show in ploT?

So i have this code here that finds the centroids of blobs within my image and then shows the image with the borders outlined and with the blobs numbered. I was wondering if it is possible to change the color of those numbers from its default black to say white.

I think it has to do with something in this line:

    text(matchCentroid(1) + labelShiftX, matchCentroid(2), num2str(k), 'FontSize', fontSize, 'FontWeight','Bold');

But here is the segment of the code I am working with.

matchMeasurements= regionprops(PI,'all');
M=length(matchMeasurements);
for    k=1:M
matchCentroid = matchMeasurements(k).Centroid; % Get centroid.
matchOrientation = matchMeasurements(k).Orientation;
  fprintf(1,'\n#%2d          %8.1f %8.1f        %8.1f            %8.1f\n', k, matchCentroid, matchOrientation); %Displays the coordinates and bacteria number.
matchCentroid = matchMeasurements(k).Centroid;   % Get centroid.
end
figure(7)
imshow(PI)
title('Bacteria Locations')

labelShiftX=-8;
fontSize=12;

for k = 1 : M  % Loop through all blobs.
  matchCentroid = matchMeasurements(k).Centroid; %Get centroid.
  text(matchCentroid(1) + labelShiftX, matchCentroid(2), num2str(k), 'FontSize', fontSize, 'FontWeight','Bold');
end
hold on;
boundaries1 = bwboundaries(PI);   
numberOfBoundaries1 = size(boundaries1);
for k = 1 : numberOfBoundaries1
  thisBoundary1 = boundaries1{k};
  plot(thisBoundary1(:,2), thisBoundary1(:,1), 'red', 'LineWidth', 2);
end
hold off;

The text object in axes has a property: Color

text( ....., 'FontSize', fontSize, 'FontWeight','Bold', 'Color', [1,0,0] );
