Use .* to multiply the mask and the color image.

For example,

RGB = imread('peppers.png');
bw = im2binarize(RGB);   %find brighter parts
mask = bw(:,:,[1 1 1]);  %make the mask 3d
maskedRGB = RGB .* mask;

That sounds like a different question. There have been several previous questions about fruit detection that might help. Search for tag:fruit
