check out the columns the flowers are actually in, for instance the blue flowers would be in row 1, with the other colors being in their own individual rows.
from left to right the first flower is blue in the first column, so blue equals 1, pink is in the third, orange 5th, white 7th. so the numbers for the code are 1 3 7 5. i already opened the box so i don't remember the color order. i'm also not sure if the road counts as column, so pink and orange might be +1
