Building a passive Dim-to-Warm LED array
Here is an example of such arrangement with transistors, but i wasn't able to figure out the circuitry from the pictures:
I can just speculate that the transistor assisted circuitry is much more efficient …

Building a passive Dim-to-Warm LED array
Here is how I did it in the end,
I had to give up on using only passive circuitry, also had to use a current sense resistor. Put a LM317 regulator in series with the warm array, in current regulating …
