Blue KIVI Votives
As you see from the last photos, the limit between blue and green colours is not specific. The photos are taken in natural daylight, and the colours in my opinion are quite right here. EDIT 31.10.2019: New photos taken by better camera (OnePlus phone).
On the left side is cobalt blue Kivi, and on the right side blue/cobalt blue Kivi. As you see, the difference is quite minimal. More photos to compare appear at my Kivi Reference Site.
