Get a mask with true or false that says where your pixels are or are not. Then you can mask them out (blacken them):
% Mask the image using bsxfun() function to multiply the mask by each channel individually. Works for gray scale as well as RGB Color images.
maskedRgbImage = bsxfun(@times, rgbImage, cast(mask, 'like', rgbImage));
Also, try the Color Thresholder app on the Apps tab of the tool ribbon.
Also, see my File Exchange.
