If you are asking about the uniforms, no. But I like that they're gradually lifting the dress code to anything the characters want as long as they also wear their grade's polo and any khaki-colored bottom. Remember in season 10 even the skirts were identical?
But I digress. Until Snake pulls the gigantic stick out of his ass and learns that uniforms do not affect academic performance, freshman will always wear yellow, sophomores purple, juniors red, and seniors blue.
