How to use #8fadcb

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • White text placed on it
  • 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 #284057
Safe as a 1px border on white
No — use #7398BE

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 lightness keeps it airy and approachable.

Worth knowing

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

#8fadcb, answered

What color is #8fadcb?

#8fadcb is a light soft blue, closest to Light Steel Blue (ΔE2000 7.2). It sits at 210° on the hue wheel with 37% saturation and 68% lightness, which reads as cool.

What is the RGB value of #8fadcb?

rgb(143, 173, 203) — 143 red, 173 green and 203 blue out of 255, or 56.1% / 67.8% / 79.6% by channel.

What is #8fadcb in HSL and HSV?

hsl(210, 37%, 68%) and hsv(210, 30%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #8fadcb a light or a dark color?

It is a mid-tone. Relative luminance is 0.4004 and perceived brightness is 66%, so black text on it reaches 9.01:1.

Should I use black or white text on #8fadcb?

Black. It scores 9.01:1 against #8fadcb, versus 2.33:1 for white — AAA at any size.

Is #8fadcb accessible on a white background?

#8fadcb on white scores 2.33:1, which fails WCAG AA at every size. Darken it to #4D7AA7 to reach 4.5:1, or #3A5B7D for 7:1.

What is the complementary color of #8fadcb?

#CBAD8F sits directly opposite on the wheel. Softer options are the split-complements #CB8F8F and #CBCB8F, which give the same contrast with far less vibration.

What colors go well with #8fadcb?

For interface work: #F5F7FA as the surface, #C7D6E5 for borders, #4B739B for secondary text, #8F513D as an accent and #284057 for hover and pressed states. For a palette, the analogous pair #8FCBCB and #8F8FCB stays calm, while #CBAD8F is the loudest partner.

What is #8fadcb in CMYK for printing?

cmyk(30%, 15%, 0%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #8fadcb warm or cool?

Cool — it scores 100 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8F97CB; nudged cooler, #7C9FC5.

Which Tailwind color is closest to #8fadcb?

The sky family — its 500 step is #0ea5e9, ΔE2000 12.4 away. That is a visible difference, so define #8fadcb as a custom token rather than reaching for the built-in.

How do I use #8fadcb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#8fadcb] or text-[#8fadcb], 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 #8fadcb with 50% opacity?

rgba(143, 173, 203, 0.5), or #8fadcb80 in eight-digit hex. Over white that composites to #C7D6E5; over black, #485766.

Is #8fadcb a web-safe color?

No. The nearest web-safe colour is #9999CC, ΔE2000 11.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #8fadcb 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 #8fadcb?

The safest is same-hue elevation: linear-gradient(135deg, #B9CBDE, #8fadcb 45%, #284057). For more colour, a short hue run to #8C7AC1 keeps it rich without turning muddy.
