% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);
% Now change the blue channel in whatever way you want.
blueChannel = whatever.........
% Then recombine into the new color image.
rgbImage = cat(3, redChannel, greenChannel, blueChannel);

blueChannel = uint8(single(blueChannel) + 255*BX/100);
Then recombine and show the final image:
imshow(rgbImage);
