Yes, I meant one with the yellow strip.
I'm not clear on what you are trying to describe with the 'blue' gouramies. Do you have pics?
Regardless, there is no 'fixed' name for the color morphs and many stand half-way between. When I say 'blue' I'm reffering to the color blue - not the pattern (e.g. 'opaline' is a pattern, not a color). The exact shade of blue doesn't matter to me - they are either going to be 'blue' or they are going to be 'gold/platinum'.
If you are reffering to the names regularly used to describe popular color morphs (so not just looking at the actual base color like I do), 'blue' is used to describe the natural pattern (two dark spots - one on caudal peduncle, one on operculum) combined with a pale blue-silver color. This isn't strictly speaking the 'wild' color, however, as wild three-spots are actualy greenish. Anyway, this isn't important. You can choose to call your gouramies' colors whatever you like. There is no 'standard'.
