How to use #7d7baf

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

Works well for
  • Headings from 24px up on white

  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • 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 #31304F
Safe as a 1px border on white
Yes

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.

What each alpha value actually composites to. The top row is #7d7baf 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.

#7d7baf, answered

What color is #7d7baf?

#7d7baf is a balanced soft blue, closest to Medium Purple (ΔE2000 10.2). It sits at 242° on the hue wheel with 25% saturation and 58% lightness, which reads as cool.

What is the RGB value of #7d7baf?

rgb(125, 123, 175) — 125 red, 123 green and 175 blue out of 255, or 49% / 48.2% / 68.6% by channel.

What is #7d7baf in HSL and HSV?

hsl(242, 25%, 58%) and hsv(242, 30%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #7d7baf a light or a dark color?

It is a mid-tone. Relative luminance is 0.2162 and perceived brightness is 51%, so black text on it reaches 5.32:1.

Should I use black or white text on #7d7baf?

Black. It scores 5.32:1 against #7d7baf, versus 3.94:1 for white — AA at any size.

Is #7d7baf accessible on a white background?

#7d7baf on white scores 3.94:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #706EA7 to reach 4.5:1, or #545287 for 7:1.

What is the complementary color of #7d7baf?

#ADAF7B sits directly opposite on the wheel. Softer options are the split-complements #AF977B and #93AF7B, which give the same contrast with far less vibration.

What colors go well with #7d7baf?

For interface work: #F6F5F9 as the surface, #CDCCE0 for borders, #59578F for secondary text, #837649 as an accent and #31304F for hover and pressed states. For a palette, the analogous pair #7B93AF and #977BAF stays calm, while #ADAF7B is the loudest partner.

What is #7d7baf in CMYK for printing?

cmyk(29%, 30%, 0%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #7d7baf warm or cool?

Cool — it scores 72 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #907BAF; nudged cooler, #798BB1.

Which Tailwind color is closest to #7d7baf?

The slate family — its 500 step is #64748b, ΔE2000 10.9 away. That is a visible difference, so define #7d7baf as a custom token rather than reaching for the built-in.

How do I use #7d7baf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7d7baf] or text-[#7d7baf], 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 #7d7baf with 50% opacity?

rgba(125, 123, 175, 0.5), or #7d7baf80 in eight-digit hex. Over white that composites to #BEBDD7; over black, #3F3E58.

Is #7d7baf a web-safe color?

No. The nearest web-safe colour is #666699, ΔE2000 8.5 away. The palette only matters for legacy displays and some email clients now.
