Differences in yellow mucus and green mucus

Sometimes our chest feel congested but not sick. Having phlegm or mucus since birth, I have been spending a lot of my time in finding out ways to deal with it. But when I see the green mucus/phlegm in chest coming out from my mouth, I got to know it has colors too. So all of this started with my life and today I am at a stage where I am always finding out what is my yellow mucus saying and what is an indication coming from my greenish mucus?

I have paid greater attention to this topic and all my research is as below!

Prior to moving ahead, lets’ first understand what mucus and phlegm is? Are you having bloody mucus? If this is your case, just stop reading and visit your nearest doctor.

My research continued with it and I found the mucus isn’t noticeable in our regular routine. But facing sickness changes its’ texture to being thick and of course changes in colors.

The surprising part is that the change in color has a lot to do with our health. The color mainly has details about what is going on with the inner organs including lungs.
