About Color Nonograms

Every puzzle in this collection depicts an official national flag drawn precisely on a 30 × 20 pixel grid.

How Nonograms Work:

• The numbers along the top (X-axis) and left (Y-axis) describe consecutive blocks of colored squares in that specific column or row, read top-to-bottom and left-to-right.
• Each clue's digit indicates the continuous run length, and its text color denotes the exact paint color.
• Consecutive runs of the same color must be separated by at least one blank (white) square.
• Consecutive runs of different colors do not require a blank space between them and can touch directly.

Solving Method:

• Overlapping Blocks: When a clue length exceeds half the line length, counting forward from the start and backward from the end creates overlapping squares that must belong to that color.
• Edge Anchoring: Clues aligned to the start or end of a completed run can be extended directly outward into known cells.
• Cross-Referencing: Combine row deductions with column clues to continuously eliminate contradictions and reveal the full flag image.

Navigation & Controls:

• Use the Paint / Pan toggle, Undo, and + / − Zoom buttons to manage precision drawing and viewing.
• On mobile devices, panning across the puzzle board can also be accomplished directly by swiping along the gray color axis clue panels.
