Here, first you need to go to the far end of the table on the left. Look underneath and you will find a gold ring taped with the number “8”, written in Blue, beside it. Take the ring and remember the color and the number. Now go to the box on the table and use the gold ring to unlock it. There is a key inside with the number “7”, written in white, beside it. Take the key and remember the color and the number. Next, check the potted plant. Behind it you will find the number “3” written in Red. You can find the last number by checking the left corner of the table. The number “6” is written, in Yellow, underneath it.
Now you have the following numbers:
Blue 8
White 7
Red 3
Yellow 6
Go to the small keyhole underneath the painting next to the elevator doors. Use the golden key to reveal a safe. You need a 4-digit code to unlock this safe. Now input the numbers with respect to the color combination. So the order will be: 7863. As you do this, the safe will open and you can take the key from inside. Go to the small keyhole on the elevator button and use this key to unlock the elevator doors and escape this floor.
