blue, pale
蒼 centers on a muted, pale blue, often associated with the color of the sky, distant mountains, or a pallid complexion.
蒼 combines 艹 (grass/plants) with 倉, which likely contributes the sound. The association with pale blue may come from the color of certain plants or the sky seen through vegetation.
Picture a pale blue sky peeking through a canopy of grass 艹 above a storehouse 倉. The grass filters the light, giving it a soft, pale blue hue.
For ソウ, imagine a soul (ソウ) painted in pale blue, floating gently above the grass and storehouse. The soul's color is the pale blue of 蒼.
