The bug
Maps placed in item frames show some strange shading problems, depending on their rotation:
18w21b, 18w22b and later:
Not rotated: All map pixels appear normal, but banner marker icons are shaded dark
Rotated by 90 or 270°: Everything looks normal, unless you move your mouse over an inventory item (which causes dark shading of the map)
Rotated by 180°: All map pixels and icons are shaded dark except for banner marker icons
18w22a:
Not rotated: All map pixels appear normal, but banner marker icons are shaded dark
Rotated by 90°: Everything looks normal
Rotated by 180°: All map pixels and icons are shaded dark except for banner marker and map position arrow icons
Rotated by 270°: All map pixels appear normal, but map position arrow icons are shaded dark
This issue is almost certainly an unintended side effect of the fix of MC-72866 in the previous snapshot.

@unknown, it is already marked as affected for this particular version. Check the 'Affects Version/s'-list before commenting.
The maps change colour/shade when the player looks at them from inside their inventory too. Just move the mouse or cursor over items and blank areas inside the inventory.
Good observation @unknown, seems to happen only at 90° and 270° rotations of the map. Updated the description to mention that.
More: orientation and time of day affect map and banner pins too.
Orientation also affects banners "pinned" in the map, lime green turning dark green in certain orientations.
Also, one map kept showing up dark when placed during the night. After sleeping and making it day, the map placed with proper color, so time of day affects the shading too somehow.
Updated description to mention some minor differences of this issue in 18w22a (map position arrows now affected too at certain rotations).
