Answer 1

Mask the RGB image

% Mask the image using bsxfun() function
maskedRgbImage = bsxfun(@times, rgbImage, cast(~mask, 'like', rgbImage));

Note that I used ~ to invert the mask so we will keep anything that is black, and remove (blacken) anything that is white in your mask from the RGB image.
