USCIS processing dates in two colors green/yellow????

[atique rahman]

Anybody has any idea why the processing dates from USCIS website got two colors green & yellow??? If you notice in USCIS website under Nebraska Service Center processing time some are in green & others are yellow. Does that mean anything? Please share your thoughts.
Atique.

I think its just to group the different forms. i.e. all i-131's are green then the next group of forms i-140's are yellow. It just make the list easier to read.
