Coming back to this puzzle I made

[jollysunflora]

There are twelve rows and columns, and there are twelve colors. A color can only appear once in any given row or column. Each of the twelve "tokens" (e.g. mary, jordan) must be assigned a color, and they must be paired with each of the twelve colors.

The white cells are the ones that need a color assignment, and when all the remaining white cells have been assigned a color and the above constraints are still true, the puzzle is solved.

I just want to know if with these constraints the puzzle is solvable or if I need to add another color and column.

Consider posting your puzzle in another format. Perhaps a spreadsheet file, or a text file. This'll make it easier for some people to attempt it. Otherwise, a solver will have to reproduce/retype it themselves to work with it on a computer.

I think you will have better luck solving this if you have an odd number of rows and columns.
