Making a new Colored "TIF" and "RGB" image out of Landsat-8 Geotiff image(11 separate bands)

Hi There,
I've downloaded a Landsat-8 image from USGS website, and now I have all the 11 bands(12 images and Metadata file), But all of them are gray-scale images, I want to:
1. Create an RGB Image and, 2. Create a new colored TIF image
out of proper bands,
To the best of my knowledge, color channels/Bands are as follows: Blue: Band_2 Green: Band_3 Redd: Band_4.
In order to make an RGB file I tried to combine them using the following code:
File_Name = File_Name_B2.TIF
[B2, ~] = geotiffread(File_Name);
File_Name = File_Name_B3.TIF
[B3, ~] = geotiffread(File_Name);
File_Name = File_Name_B4.TIF
[B4, ~] = geotiffread(File_Name);
RGB_Image = cat(3, B4, B3, B2);
but result image is still in gray-scale format.
Any help is appreciated.

I wrote a function to do this for Landsat 8, but it's basically the same method you use. Check out L8read.

Without an example it's hard to know exactly what's going on. Are you sure it's not just low light that makes it appear grayscale? Try
RGB_Image = L8read(Folder_name,'stretch');
