Description

using LightGraphs, GraphPlot;
using Colors;

n = 198
graph = barabasi_albert(n, 3, 3)

mapping = ones(n)
mapping[1:100] .= 2

nodecolor = [colorant"green", colorant"red"]
nodefillc = nodecolor[convert(Array{Int}, mapping)]
gplot(graph, nodefillc=nodefillc)

--> all nodes are black
if n<197 --> nodes are green and red

Research direction

Run the issue's Julia snippet through the gplot entry point with n=198, then compare it with the n<197 case to isolate the threshold behavior. Trace the rendering path used by GraphPlot and verify that the requested green and red node colors are preserved for all 198 nodes.
