Straightforward Aizome

#b0c4e5
Notes

Straightforward Aizome (#B0C4E5) is a soft azure with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (217°, 50%, 79%) places it in the balanced band at a light lightness. It works as a background wash, large-area fill, or soft illustration tone. Add a darker ink of the same hue when you need type over it. For a confident two-color system, pair it with its complementary amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Aizome
noun

The Japanese traditional indigo-dyeing technique — aizome — using Persicaria tinctoria (Japanese indigo) and natural fermentation in clay vats. The dyer is called aishi (indigo master), trained over decades. The color refers to a freshly aizome-dyed cotton: a saturated, slightly cool deep blue with the matte finish of multi-bath natural-indigo dye.
