Out of Sight Description

Out of Sight is a puzzle inspired from nikoli’s Hitori. The object is to shade in some of the grid squares. No two shaded squares should be adjacent, and all of the unshaded squares should be in one contiguous region – equivalently, any two unshaded squares should have a path joining them through adjacent unshaded squares. Furthermore, any unshaded arrow should not point to any unshaded cells with a symbol (dot or arrow) of the same color, where arrows are allowed to point past shaded squares. The solution is unique.

Below is an example puzzle and its only solution.
