About this color
Calm that earns trust
Medium Blue is #778899, a Blue tone with a clear cultural lineage. Read on its own it belongs to the Blue family; read through its digital color roots, it carries a second layer of meaning.
Design tip
Test Medium Blue (#778899) on a neutral surface first; a Blue accent then looks intentional rather than decorative.
Best use
Give Medium Blue the single element that must be noticed first, and let the rest of the Blue palette support it.

Design guidance
How to make it work
Do
- Keep saturated fills below about twenty percent of the layout.
- Use it for the primary call to action and nothing else.
- Check the pairing at small sizes on a neutral background.
Avoid
- Do not place it beside clashing neon greens or electric blues.
- Never use it for long body text on white.
- Avoid gradients that shift its hue into another family.
Brands built on The Ruler, The Sage use it to signal character before they say a word.
Blue recedes and steadies, which makes it the default for interfaces and institutions. Its range runs from near-black navy to pale sky without ever losing composure.

History
Pigments and provenance
Before synthetic dyes, Medium Blue was matched with mineral and plant pigments, and the Blue family depended on sources such as ochre, madder and indigo. Screens now reproduce it more consistently than any single pigment ever could.

RAL Classic
Can three steps of one hue work together
Three steps from the 50–950 scale of “Medium Blue”: same hue, only lightness differs. Below is the contrast whenever one of them is text on another.
- 200 ↔ 500: 2.42:1 (FAIL)
- 500 ↔ 800: 2.74:1 (FAIL)
- 200 ↔ 800: 6.65:1 (AA)
Pairs reaching 4.5:1 (AA body text): 1 of 3. Pairs reaching 3:1 (large text, icons, borders): 1 of 3. The rest fall below 3:1 and should not carry text.
Color combinations
Rotate the hue wheel while holding lightness steady.
How to use it
Three moves keep the color readable and deliberate.
Why it works
The perceptual reasoning behind the palette.
All six palettes rotate hue at similar lightness, so the best in-group contrast falls between 1.00:1 and 1.71:1. Use them for fills, charts and graphics rather than as text on each other — when you need text, use a neutral or a darker step of the same scale.
Complementary
Opposite the hue wheel; it sharpens the focal color by contrast.
Best use: Calls to action and single-feature highlights
Split-complementary
Two neighbors of the opposite hue; softer than a direct complement.
Best use: Balanced marketing layouts with two accents
Triadic
Three hues spaced evenly; lively but needs one dominant voice.
Best use: Event identities and playful editorial spreads
Analogous
Neighbors on the wheel; quiet, cohesive and easy to scan.
Best use: Backgrounds, charts and calm product pages
Monochromatic
One hue across lightness steps; disciplined and premium.
Best use: Design systems, packaging and typographic hierarchy
Tetradic
Two complementary pairs; rich, but requires strict proportion.
Best use: Complex dashboards and multi-service brands

WCAG contrast standards
WCAG 2.2 sets minimum contrast for text and interface parts. #778899 measures 3.64:1 against white (FAIL) and 5.18:1 against black (AA). Use the table below to choose the right threshold for the text size.
| Level | Normal text | Large text (18pt+ / 14pt bold) | Icons & UI parts |
|---|---|---|---|
| AAA | 7 : 1 | 4.5 : 1 | — |
| AA | 4.5 : 1 | 3 : 1 | 3 : 1 |
| Fails | < 4.5 : 1 | < 3 : 1 | < 3 : 1 |
Large text means 18pt regular or 14pt bold. UI parts need 3:1 against adjacent colors. AA is the common compliance baseline; AAA is enhanced.
