Dude, an object can be transparent, translucent or opaque. Transparent objects allows 100% light to pass through making the object nearly invisible and objects behind it more clearly visible and the same is oppositely true for opaque. Translucent objects are somewhere between transperent and opaque. I do agree that Airtel's logo is translucent, but their logo is near opacity and not towards transperancy. The difficulty in viewing the objects behind is where the level of opacity comes into play. They can definitely choose an appropriate level where both the object (Airtel's Logo) and the objects behind (Channels) clearly visible to some extent.
