Yellow is a cool color in grasses! It brightens up a shady corner and makes a good contrast with the many shades of green in other plants. Spring is often when yellow grasses are showiest, some fade to green as the season continues, like Bowles golden or wood millet or Carex lupulina, hop sedge, shown here. Wood millet is a bunch grass, native to Europe, while hop sedge has slowly creeping rhizomes and is native to the US. Both of these grasses grow in full to light shade. Hop sedge and wood millet are very yellow, and can brown in full sun.
