Hi @alizasnow

If the rows in your dataset are labeld as positive or negative you can use this column in the Color Manager Node.
Then in the Tag Cloud there is an option Where you can assign: use row color property.
The size of the words will come from the TF node (in this example) and the colors from the ColorManager.
