What kind of path is this?

I am colorblind a bit, but I really can't find this path color in the path color legenda...

I am seeing some un-natural slowness in the outer perimeter, while the much faster inner perimeter prints at nice evenly speed. Also I see the fan fluctuating a bit, I think it has the same cause. And I am seeing a bit of a distortion in printquality at some of these spots. Anyone an idea about this?

Is there an overhang in that area? Looks like the cooling settings are kicking in.

I wasn't colorblind before KISSLicer, that confuses me a bit too I suspect it's unsupported area and you can check by changing display to "Material" or "Extruder" in which case unsupported tinting stays.

You probably have to increase the "Cool [mm^3/s]" value at tha "Matl" tab under "Flow Adjust", in order to maintain the speed you want.
You can also set the "Fan / Cool" settings to the same values, if you do not want to have the fan fluctuating.
