Color meter reading for Dirty Flourescents

[Ronald Gerald Smith]

I have just bought the Sekonic Prodigi C-500 and have been walking around the house with it.

 

I have been examining it under flourescents and I am seeing the CC index "1M" which is basically telling me that there is some green and that I might want to add 2.5CC Filter correction number of green.

Also I have been seeing the "1M" even when there are no flourescents and I am just walking around inside the house with coffee color walls and dark brown floors in normal daylight

 

I wanted to know your opinions - would 1M really matter? Would it be enough to cause you to start correcting green with gels or on-camera filters? How about 2M? If not, then where would you really start to correct the green?

 

I know that this is somewhat subjective but I wanted to know what the general opinion was about this.
