im = imread('Picture1.png'); I = rgb2gray(im); imshow(im); rgbImage = ind2rgb(I, jet(256)); imshow(rgbImage); maskedImage = double(repmat(rgbImage, 1, 1, 3)); imshow(maskedImage);

Read this to format your code. Then be sure to use the green and brown picture frame icon to insert your picture into your post.
And explain what "remove" means to you. Do you mean crop? Do you mean blue goes to black? What???
