Assume you want 40 colors, get a basic color palette from RcolorBrewer, and use colorRampPalette to interpolate

# Brewer palette Paired 12
pal12 = c("#A6CEE3", "#1F78B4", "#B2DF8A", "#33A02C", "#FB9A99", "#E31A1C", "#FDBF6F", "#FF7F00", "#CAB2D6", "#6A3D9A", "#FFFF99", "#B15928") colorRampPalette(pal12)(40)
