How to use #809abc

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 #2C3D53
Safe as a 1px border on white
No — use #7D97BA

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.

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.

#809abc, answered

What color is #809abc?

#809abc is a balanced soft blue, closest to Cornflower Blue (ΔE2000 7.4). It sits at 214° on the hue wheel with 31% saturation and 62% lightness, which reads as cool.

What is the RGB value of #809abc?

rgb(128, 154, 188) — 128 red, 154 green and 188 blue out of 255, or 50.2% / 60.4% / 73.7% by channel.

What is #809abc in HSL and HSV?

hsl(214, 31%, 62%) and hsv(214, 32%, 74%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #809abc a light or a dark color?

It is a mid-tone. Relative luminance is 0.3133 and perceived brightness is 59%, so black text on it reaches 7.27:1.

Should I use black or white text on #809abc?

Black. It scores 7.27:1 against #809abc, versus 2.89:1 for white — AAA at any size.

Is #809abc accessible on a white background?

#809abc on white scores 2.89:1, which fails WCAG AA at every size. Darken it to #5678A4 to reach 4.5:1, or #415A7C for 7:1.

What is the complementary color of #809abc?

#BCA280 sits directly opposite on the wheel. Softer options are the split-complements #BC8480 and #B8BC80, which give the same contrast with far less vibration.

What colors go well with #809abc?

For interface work: #F5F7FA as the surface, #CAD5E3 for borders, #4F6E96 for secondary text, #8A5942 as an accent and #2C3D53 for hover and pressed states. For a palette, the analogous pair #80B8BC and #8480BC stays calm, while #BCA280 is the loudest partner.

What is #809abc in CMYK for printing?

cmyk(32%, 18%, 0%, 26%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #809abc warm or cool?

Cool — it scores 92 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8084BC; nudged cooler, #6D8FB5.

Which Tailwind color is closest to #809abc?

The blue family — its 500 step is #3b82f6, ΔE2000 11.3 away. That is a visible difference, so define #809abc as a custom token rather than reaching for the built-in.

How do I use #809abc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#809abc] or text-[#809abc], 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 #809abc with 50% opacity?

rgba(128, 154, 188, 0.5), or #809abc80 in eight-digit hex. Over white that composites to #C0CDDE; over black, #404D5E.

Is #809abc a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 9.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #809abc 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 #809abc?

The safest is same-hue elevation: linear-gradient(135deg, #A8BAD1, #809abc 45%, #2C3D53). For more colour, a short hue run to #826CB1 keeps it rich without turning muddy.
