You can use the series.<series index>.color option to assign a specific color to a specific series, and as long as you keep track of which series are being used in a given chart, you can keep your colors consistent.

Currently I don't think it's not possibly to bind a color to a specific category (column/color in the legend). If I have 5 categories, I will need to add an array of colors for them. However, if my chart is dynamic and doesn't always have 5 categories (one missing in the middle) - this will change the color each category receives. This can be confusing to users.
