We analyze the constraints on colored scalar bosons imposed by the current LHC data at $\sqrt{s}=13\mathrm{TeV}$. Specifically, we consider an additional electroweak doublet of color-octet scalars, satisfying the principle of minimal flavor violation in order to fulfill the stringent experimental limits on flavor-changing neutral currents. We demonstrate that colored scalars with masses below 800 GeV are already excluded, provided they are not fermiophobic.
