Klinefelters?

I am not aware of colorblindness being related to KS. but, i guess anything is possible.
I suggest you to bring up your concerns to your doctor at your next check-up. But, don't worry yourself too much. If you are able to function daily like a normal teenager, it's probably not KS.
Feel free to ask me any other questions you may have.
Best regards,
