Life is Strange: True Colors

After the sequence where Steph meets Alex in her apartment where she needs to cheer Steph up (I chose to play her in Foosball), go up to roof of your apartment by walking over to the stairs and pressing "A". Once there, turn left out of the door and walk towards the flowerbeds on your left hand side. Towards the end of the flowerbed, you'll see an indicator for a "Button". Hold "LT" and the "A" button, listen to memory play out and the achievement will pop!
