Hey, it would be nice if you could support more modded entities e.g. pipes from bob's. I suggest replacing the lines 15-20 in data-updates.lua with the following. I also added pumps and made pumps and storage tanks a darker purple, similar to underground belts and splitters.

for _, v in pairs(data.raw["pipe"]) do
v.friendly_map_color = {r = 0.29, g = 0.09, b = 0.56} -- 74, 23, 143
end

for _, v in pairs(data.raw["pipe-to-ground"]) do
v.friendly_map_color = {r = 0.29, g = 0.09, b = 0.56} -- 74, 23, 143
end

for _, v in pairs(data.raw["pump"]) do
v.friendly_map_color = {r = 0.23, g = 0.07, b = 0.45}
end

for _, v in pairs(data.raw["storage-tank"]) do
v.friendly_map_color = {r = 0.22, g = 0.07, b = 0.42}
end

for _, v in pairs(data.raw["heat-pipe"]) do
v.friendly_map_color = {r = 0.56, g = 0.0, b = 0.0} -- 142, 0, 0
end

for _, v in pairs(data.raw["reactor"]) do
v.friendly_map_color = {r = 0.16, g = 0.73, b = 0.15} -- 41, 186, 37
end

hello, it looks like you can submit a pull request at the project's github page, available in the 'source' link here on the mod info page.
