The Cave is black, scary and unknown(the black overlapping figure). When you enter the cave, you feel fear(black). But under the fear there is hope and curiosity (blue smudges at the bottom). Those two takes you deeper and deeper inside.You think you will find something interesting, if not valuable(yellow background in the upper right). And when you return from your adventure, you are hoping you will sit with your friends, drink wine(burgundy on the left side) and tell stories about the cave. The overall figure looks like a slice of bread. Black bread. It's just a reminder that it is dangerous and you can get "burned" any minute. But it's like food for you, you cannot live without adventures.
