So today i decided to attempt puzzle constructing-for the very first time.
The three puzzles below contain a hidden symbol, each symbol is somewhat related to one another. Use the arrows to find out the identity of each puzzle. Then come to a conclusion of what the 4th symbol would be if it had a puzzle.
the specific colors of the dots do not matter. But color matters
Hint 2, even more hintier
just because you can't see it, doesn't mean that it's not there.
Don't pick up your pencil
