Preview a color combination round by round, before you commit any yarn.
Choosing colors for a granny square is a lot easier when you can actually see the layout before buying yarn. Set the number of rounds your square will have, assign a color to each one, and this planner renders a live preview so you can try different combinations — swap a color, and the square updates instantly.
How many colors should a granny square have?
Classic granny squares often use 3-4 colors plus a neutral border, but there is no fixed rule — some of the most striking designs use just two contrasting colors repeated across all rounds.
Should every round be a different color?
Not necessarily — repeating a color every other round, or using one color for multiple consecutive rounds, both create appealing effects. Use this planner to preview a few combinations before committing.
How do I plan colors for many squares that need to look cohesive?
Pick a small shared palette (4-6 colors) and vary which color goes in which round from square to square — this creates visual variety while keeping the whole blanket feeling unified.
