Steps:

1. Get the Centre Blobs
2. Make it color as per your requirements, please note that resultant color image will be RGB image, not binary

Here, bwImage represents the binary image

bwImage=bwareafilt(~bwImage,1);
bChannel=255*uint8(bwImage);
gChannel=255*ones(size(bwImage),'uint8'); 
colorImage=cat(3,bChannel,gChannel,gChannel);
imshow(colorImage);

Hope it Helps!
