How to use #709cbf

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #274358
Safe as a 1px border on white
No — use #6C9ABD

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

Worth knowing

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

Transparency

What each alpha value actually composites to. The top row is #709cbf over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#709cbf, answered

What color is #709cbf?

#709cbf is a balanced soft blue, closest to Cornflower Blue (ΔE2000 6.5). It sits at 207° on the hue wheel with 38% saturation and 59% lightness, which reads as cool.

What is the RGB value of #709cbf?

rgb(112, 156, 191) — 112 red, 156 green and 191 blue out of 255, or 43.9% / 61.2% / 74.9% by channel.

What is #709cbf in HSL and HSV?

hsl(207, 38%, 59%) and hsv(207, 41%, 75%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #709cbf a light or a dark color?

It is a mid-tone. Relative luminance is 0.3098 and perceived brightness is 58%, so black text on it reaches 7.20:1.

Should I use black or white text on #709cbf?

Black. It scores 7.20:1 against #709cbf, versus 2.92:1 for white — AAA at any size.

Is #709cbf accessible on a white background?

#709cbf on white scores 2.92:1, which fails WCAG AA at every size. Darken it to #497BA4 to reach 4.5:1, or #365C79 for 7:1.

What is the complementary color of #709cbf?

#BF9370 sits directly opposite on the wheel. Softer options are the split-complements #BF7074 and #BFBB70, which give the same contrast with far less vibration.

What colors go well with #709cbf?

For interface work: #F4F8FA as the surface, #C7D8E6 for borders, #4B779B for secondary text, #C37D6C as an accent and #274358 for hover and pressed states. For a palette, the analogous pair #70BFBB and #7074BF stays calm, while #BF9370 is the loudest partner.

What is #709cbf in CMYK for printing?

cmyk(41%, 18%, 0%, 25%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #709cbf warm or cool?

Cool — it scores 99 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #707FBF; nudged cooler, #5C8AB9.

Which Tailwind color is closest to #709cbf?

The sky family — its 500 step is #0ea5e9, ΔE2000 8.7 away. That is a visible difference, so define #709cbf as a custom token rather than reaching for the built-in.

How do I use #709cbf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#709cbf] or text-[#709cbf], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #709cbf with 50% opacity?

rgba(112, 156, 191, 0.5), or #709cbf80 in eight-digit hex. Over white that composites to #B8CEDF; over black, #384E60.

Is #709cbf a web-safe color?

No. The nearest web-safe colour is #6699CC, ΔE2000 3.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #709cbf mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this moderate chroma the association is present but not shouted.

What gradient works with #709cbf?

The safest is same-hue elevation: linear-gradient(135deg, #9AB9D2, #709cbf 45%, #274358). For more colour, a short hue run to #6C5BB6 keeps it rich without turning muddy.
