How to use #7170bf

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

Works well for
  • Headings from 24px up on white
  • 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
  • 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 #282758
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.

#7170bf, answered

What color is #7170bf?

#7170bf is a balanced soft blue, closest to Slate Blue (ΔE2000 7.8). It sits at 241° on the hue wheel with 38% saturation and 59% lightness, which reads as cool.

What is the RGB value of #7170bf?

rgb(113, 112, 191) — 113 red, 112 green and 191 blue out of 255, or 44.3% / 43.9% / 74.9% by channel.

What is #7170bf in HSL and HSV?

hsl(241, 38%, 59%) and hsv(241, 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 #7170bf a light or a dark color?

It is a mid-tone. Relative luminance is 0.1886 and perceived brightness is 49%, so black text on it reaches 4.77:1.

Should I use black or white text on #7170bf?

Black. It scores 4.77:1 against #7170bf, versus 4.40:1 for white — AA at any size.

Is #7170bf accessible on a white background?

#7170bf on white scores 4.40:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #6D6CBD to reach 4.5:1, or #4E4CAB for 7:1.

What is the complementary color of #7170bf?

#BEBF70 sits directly opposite on the wheel. Softer options are the split-complements #BF9970 and #96BF70, which give the same contrast with far less vibration.

What colors go well with #7170bf?

For interface work: #F5F4FA as the surface, #C7C7E6 for borders, #4C4B9B for secondary text, #917C3B as an accent and #282758 for hover and pressed states. For a palette, the analogous pair #7096BF and #9970BF stays calm, while #BEBF70 is the loudest partner.

What is #7170bf in CMYK for printing?

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

Is #7170bf 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 #8E70BF; nudged cooler, #6E89C1.

Which Tailwind color is closest to #7170bf?

The indigo family — its 500 step is #6366f1, ΔE2000 8.2 away. That is a visible difference, so define #7170bf as a custom token rather than reaching for the built-in.

How do I use #7170bf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#7170bf] or text-[#7170bf], 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 #7170bf with 50% opacity?

rgba(113, 112, 191, 0.5), or #7170bf80 in eight-digit hex. Over white that composites to #B8B8DF; over black, #393860.

Is #7170bf a web-safe color?

No. The nearest web-safe colour is #6666CC, ΔE2000 4.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #7170bf mean?
