Using Get Color activity, am getting wrong color

am having all sheets of excel in one list variable
using for each, am performing following step for each sheet
am reading data from excel sheet and storing it in a datatable , need to get color from each row of particular column if it has green color am adding it to another datatable and performing rest of the steps, it is working good as expected atlast clearing datatable.
But when am doing same step for next sheet of same excel , its giving wrong color

Can I see the workflow may be as a screenshot if possible


will get correct color for first sheet but for next sheet it will provide wrong color
