How to use #7f8eb6

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

  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care

  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
24px / 18.66px bold
Safe as a fill behind white type
No — use #2E3851
Safe as a 1px border on white

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.

#7f8eb6, answered

What color is #7f8eb6?

#7f8eb6 is a balanced soft blue, closest to Light Slate Gray (ΔE2000 8.9). It sits at 224° on the hue wheel with 27% saturation and 61% lightness, which reads as cool.

What is the RGB value of #7f8eb6?

rgb(127, 142, 182) — 127 red, 142 green and 182 blue out of 255, or 49.8% / 55.7% / 71.4% by channel.

What is #7f8eb6 in HSL and HSV?

hsl(224, 27%, 61%) and hsv(224, 30%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7f8eb6 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2724 and perceived brightness is 56%, so black text on it reaches 6.45:1.

Should I use black or white text on #7f8eb6?

Black. It scores 6.45:1 against #7f8eb6, versus 3.26:1 for white — AA at any size.

Is #7f8eb6 accessible on a white background?

#7f8eb6 on white scores 3.26:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #6274A5 to reach 4.5:1, or #495881 for 7:1.

What is the complementary color of #7f8eb6?

#B6A77F sits directly opposite on the wheel. Softer options are the split-complements #B68B7F and #AAB67F, which give the same contrast with far less vibration.

What colors go well with #7f8eb6?

For interface work: #F5F6F9 as the surface, #CBD1E1 for borders, #536492 for secondary text, #866546 as an accent and #2E3851 for hover and pressed states. For a palette, the analogous pair #7FAAB6 and #8B7FB6 stays calm, while #B6A77F is the loudest partner.

What is #7f8eb6 in CMYK for printing?

cmyk(30%, 22%, 0%, 29%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7f8eb6 warm or cool?

Cool — it scores 83 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #847FB6; nudged cooler, #7D96B8.

Which Tailwind color is closest to #7f8eb6?

The slate family — its 500 step is #64748b, ΔE2000 11.7 away. That is a visible difference, so define #7f8eb6 as a custom token rather than reaching for the built-in.

How do I use #7f8eb6 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7f8eb6] or text-[#7f8eb6], 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 #7f8eb6 with 50% opacity?

rgba(127, 142, 182, 0.5), or #7f8eb680 in eight-digit hex. Over white that composites to #BFC7DB; over black, #40475B.

Is #7f8eb6 a web-safe color?
