I got to know the 4 question game:
1. Visualize yourself in a white room. You’re in a bed and everything is white. How do you feel?
2. What is your favorite animal? What qualities do you see it as having?
3. What is your favorite color? How does it make you feel when you think about it?
4. Imagine yourself on a beach. Nobody is around and the ocean is right in front of you. What do you do?

Should I tell the "results" of m interpretation for the girls? Cause invariably they ask what did I conclude.

You just make everything up!!!!

Answer like it was the cube routine:

1. Visualize yourself in a white room. You’re in a bed and everything is white. How do you feel?

If she feels calm...she is a pretty laid back person. If she feels happy she can be either romantic or positive girl.

2. What is your favorite animal? What qualities do you see it as having?

The qualities of the animal are the things she´d like to have...like if she likes an eagle...she wants to be more free in her life and stuff like that. If she says bunny or other cute animal...she is inmature...or might be consider an IOI...cause she is showing off her femininity

3. What is your favorite color? How does it make you feel when you think about it?

The same as the cube...

4. Imagine yourself on a beach. Nobody is around and the ocean is right in front of you. What do you do?

This one tells if she is a active or passive person... if she is...surfing, she is pretty active, and if she is just sunbathing, she is laid back and passive.

or... you can interrupt the game negging her, or commenting of something interesting she had just said.

I will reformulate my question should I inform the girl of my conclusions or keep it for me?

Inform her gad damn it! That is why you coldread.
Coldreading isnt really reading them for real. Take 20 facts that are true for most women and tell the girl you can see that in her.
Could be as easy as this. Personality: You are a passionate person who loves to be involved in things you like. For most of the time you act a bit tough, but on the inside all you really want is people to be nice to you and you are afraid that if you dont act the way you do people might hurt you. For most of the time you dont take chances and do the thing you really want, but there are moments when you feel like you can do anything. That is when your the most happy, becouse this is who you really are.

You see! That was 3 or 4 facts. Imagine 20. She will feel like you have super powers!

You should inform her about your conclusions....

But you cant get much info of about her, just with cold reading.

Body language, and plain old experience tells you really what you need to know about a girl...cold reading is more a "girl entretainer".
