The thermal relic abundance of Dark Matter motivates the existence of newelectroweak scale particles, independent of naturalness considerations.However, most unnatural Dark Matter models do not ensure the presence of newparticles charged under SU(3)_C, resulting in challenging LHC phenomenology.Here, we present a class of models with scalar electroweak doublet Dark Matterthat require a host of colored particles at the TeV scale. In these models, theHiggs boson is apparently fine-tuned, but the Dark Matter doublet is kept lightwithout any additional fine-tuning.Comment: 1+22 pages, 5 figures. Added references.
