Hint 04

We do need a bit of guidance with the flag semaphore language. The letter square seems to provide that guidance we seek. You know what I love most about water? It is so clear, you can almost see through it without disturbance.

Note: if you don’t have the text ‘gives guidance’ printed beside the letter square on your card, that is because we had a version mixup a while ago. In that case, take the text ‘gives guidance’ into account when puzzling your way through the letter square. We apologise for the inconvenience.

Solution of this Step
If you hold the card up to the light, you should see the weird-shaped seaweed shine through. It will indicate the letters P, U, R, P, L and E in the letter square. Now we know that Purple gives guidance.
