You didn't mention whether the site is sunny or shady so I can't make a single recommendation. However, the following is a list of plants from Colorado State University:
Groundcovers and Ornamental Grasses
Antennaria rosea (Pink Pussytoes), full sun, purple blossoms early summer, short ground cover 4-12 inches, spreads rapidly.
Bouteloua curtipendula (Sideoats, Grama Grass), full sun, green with purple tips midsummer, medium meadow grass 1-2, remarkably hardy, non-invasive.
Calamagrostis acutiflora (Karl Foerster Feather Reed Grass), full sun, green with tan tips, tall meadow grass 3-6 feet.
Cerastium tomentosum (Snow-in-summer), part to full sun, white blossoms late spring, medium ground cover 8-12 inches, can be invasive
Delosperma cooperi (Pink Hardy Ice Plant), full sun, purple blossoms late spring, ground cover 6 inches, good in hot or dry conditions.
Delosperma nubigenum (Hardy Yellow Ice Plant), full, red in winter, yellow blossoms late spring, short ground cover 1-3 inches.
