Column bar widget - color categories when there is more than one value

Usually, when you want to color categories, you would use "break by", but then you cannot have two values on the same graph:

I needed to show past year's values (grey on the left widget bellow) but on the same time color the categories like they are on the right for the sake of clarity.

I couldn't find a script that would suit and then it occured to me to apply conditional coloring according to the value in each category
