How can the color blind distinguish instinct vs mystic gym?

I am completely color blind (meaning I cannot recognize any color) and having difficulty telling apart the mystic gym vs the instinct gym.

I can clearly identify a valor gym, when I open the gym, they use dark colored fonts in the player name and pokemon info. I have no problem with valor.

But with mystic and instinct, they are hard to tell apart. They use a light colored player name over a less light level number on the upper right hand of the open gym screen.

Just wondering if anyone has any suggestions. I am not blind. My color blindness allows me to tell apart light things from dark things, but I cannot say when something is blue or yellow.

It used to be i could tell before battling if I am facing enemy or ally because I would either see 6 or 1 attackers. But now this method does not work.

The response from king14nyr and Kent has led me to a solution to the problem. The attack/train icon buttons are different and leads to a simple way to discriminate. Boxing glove is for training and the other icon with the zig zag lines or 6 pointed star is for attack.

This page has a close up of both icons in the open gym screen.
