Barley in particular is used to make miso paste (along with fermented soybeans), teas, and shouchuu (a whisky-like alcoholic beverage).
Since it is the beginning of growth, think bright blues, greys, bright green, and maybe orange and pale, rosy pinks. The days of sakura are already over, but peonies will most certainly be in! Ayame are also very much in season, so purples and white will not be out of place, either.
Browns and earth colours would bring warmth and livelihood, but as for me, I'll stick to cool colours as often as possible. Bright and cool greens are a favourite, when I think I can get away with them! Summer grasses and breezes are coming. Can you feel it?
