One Lantern Is Wrong. Can You Find It?

Six lanterns are lit. One is in the wrong square. Can you find it—and move it to the right one?
Here’s your garden. In Yodoku, every row, column and color needs exactly one lantern. Lanterns can’t touch, even diagonally.

Region letters: A (pink), B (orange), C (yellow), D (green), E (blue), F (purple). An asterisk (*) marks a lantern; a dash (—) marks a cutout.
| Row | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| 1 | A* | A | A | A | — | — |
| 2 | A | A | B* | B | — | — |
| 3 | D | D | B | B | C | C* |
| 4 | D | D* | D | C | C | C |
| 5 | — | — | D | E* | F | F |
| 6 | — | — | F | F | F | F* |
Give me a hint
Look for a column with two lanterns and a column with none. Filling the gap must also keep lanterns from touching, even diagonally.
Show the answer
Move the yellow lantern at row 3, column 6 one square left, to column 5.
Column 6 has two lanterns; column 5 has none. Moving the purple lantern at row 6, column 6 left would touch the blue lantern at row 5, column 4 diagonally. The yellow lantern can move left without touching another light.
