Hi Gianvitualno! 
The grids in the second picture are from the tutorial video. I made a grid according to object > path > split into grid as in the tutorial. but the color of my grid is black and there is a light green grid on it. how can i make the grid with the same color as the second image?

Select all green lines and go to View menu > Guides > Make Guides.
