Color Coding on Processing Time Chart

[r00724]

Hi folks,

Just curios to know if the yellow and green color coding on the processing time chart means anything? If you go to the USCIS website and pull up the processing time chart for California Service Centre, there are 2 -3 categories marked in green and rest of them are marked yellow. Not sure if that has a significant meaning?

I think it's just for readability. It does not mean anything at all.
