I was doing some color testing on lights and noticed something interesting in my readings. I can't seem to find a consistent correlation between the CCi reading and CClf. For instance, at 6000k, the light read CCi: 0.2M and CClf: 1/8 minus green but at 5600k, the light read CCi: 0.1M and CClf: 1/8 plus green. I'm not sure why this jump over the black body radiator curve in gel but not in the correction index. Any explanation for something like this? Anybody know of any deep dives into these measurements? Thanks.
