That is sexy.
But same color wire.. hmm confusing at the end point.
Colored wires definitely would be sexier. But could be too sexy ;)
PTFE isolation has its advantages and I love it. Not many colors for PTFE isolated wires. That is why here they are length-indexed - shortest is No.1, next - 2, longest is No.8. That is enough at soldering time. And even more than enough - such way is easier than to remember which color is for.
To be completely honest... the same length wires twisted in one cord result the aligned ends in case of 5 wires. in case of 8 wires one wire is in the middle and is untwisted, and thus passes a shorter path - at the end it is quite longer (in my case about 3 mm for 8 wires and 1.5mm for 6 wires) that could be corrected.
