We compute the color fields of SU(3) lattice QCD created by static pentaquark systems, in a 243\ifmmode×\else\texttimes\fi48 lattice at \ensuremathβ=6.2 corresponding to a lattice spacing a=0.07261(85) fm. We find that the pentaquark color fields are well described by a multi-Y-type shaped flux tube. The flux tube junction points are compatible with Fermat-Steiner points minimizing the total flux tube length. We also compare the pentaquark flux tube profile with the diquark-diantiquark central flux tube profile in the tetraquark and the quark-antiquark fundamental flux tube profile in the meson, and they match, thus showing that the pentaquark flux tubes are composed of fundamental flux tubes.
