Frank Lull Mint

#9eefdd
Notes

Frank Lull Mint (#9EEFDD) is a soft teal with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (167°, 72%, 78%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

Lull
modifier

Middle English lullen, to-sing-to-sleep. As a color modifier, lull implies a hushed-and-pacified-and-cradled quality, the visual register of cradle-song-and-vesper-lull hand-cradled-and-rocked cradle-and-cot-and-crib hand-rocked-and-sung-to-lulled-and-cradled lulled-and-cradled surfaces under cradle-song-and-vesper hush-and-quiet-and-still bedside-and-nursery-light. Sits at the modifier-and-mood end of the grid, parallel to hush and soothe in usage.

Mint
noun

The genus Mentha — peppermint, spearmint, apple mint, water mint — the cooling herb whose menthol gives it that quality at the molecular level. The color refers to fresh peppermint leaves before drying: a clean, slightly cool green with the matte finish of trichome-rich leaf surface. Lighter than basil, cooler than parsley, with the mojito-and-Pimm's association of a herb tied to summer drinks across two continents.
