Optifine does not make any changes - it adds some more settings
So check the settings or press F3 - on the left side, Optifine should be mentioned
In the video settings there is now a shaders button - with it you can change the look
Get some shaders as zip-files and put these to /.minecraft/shaderpacks/

You can find all CTM files in .minecraft\libraries\optifine\OptiFine\1.XX.X_HD_U_XX\OptiFine-1.XX.X_HD_U_XX.jar\assets\minecraft\optifine\ctm\default
The problem is that each glass color has 47 images and there are 17 glass colors (clear class included) so you would have to edit 799 images. Luckily there is a way for CTM to only use 5 images instead, so you only have to deal with 85 images in total.
I extracted the necessary glass images to a zip file for you, but remember not to edit the .properties files as they contain info on which glass color the images belong to: http://s000.tinyupload.com/?file_id=57231547303423168807
