Colors are difficult. The same batch will look different depending on the lighting and the thickness of the glass you look at. I mostly call anything that's light blue green in any tint an aqua.
I agree with cowseatmaise, color interpretation can be difficult, especially when looking at a picture and not the real jar. There are so many color variations out there. I am definitely no photographer but personally I find that taking pictures outside under overcast skys will give the closest and best color. If you look at my previous post ' what color is this Mason jar' ? , I was told by a professional that the color of the Mason jar was Ball Blue, making it $10-20 jar. However he came to that conclusion because of the photo I sent him. Looking back I should have taken it outside , not indoors. Having the Teal Staffords Ink next to it for comparison this time helped a great deal too. Having the correct color interpretation in some jars can make a jar worth pennies or thousands. The Red Book #10 mentions Teal as a color that is subject to wide interpretation. So sometimes it is all in the eye of the beholder...[]
