How to use #707dbb

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 #293156
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.

#707dbb, answered

What color is #707dbb?

#707dbb is a balanced soft blue, closest to Royal Blue (ΔE2000 10.4). It sits at 230° on the hue wheel with 36% saturation and 59% lightness, which reads as cool.

What is the RGB value of #707dbb?

rgb(112, 125, 187) — 112 red, 125 green and 187 blue out of 255, or 43.9% / 49% / 73.3% by channel.

What is #707dbb in HSL and HSV?

hsl(230, 36%, 59%) and hsv(230, 40%, 73%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #707dbb a light or a dark color?

It is a mid-tone. Relative luminance is 0.2170 and perceived brightness is 51%, so black text on it reaches 5.34:1.

Should I use black or white text on #707dbb?

Black. It scores 5.34:1 against #707dbb, versus 3.93:1 for white — AA at any size.

Is #707dbb accessible on a white background?

#707dbb on white scores 3.93:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #6270B4 to reach 4.5:1, or #465393 for 7:1.

What is the complementary color of #707dbb?

#BBAE70 sits directly opposite on the wheel. Softer options are the split-complements #BB8870 and #A2BB70, which give the same contrast with far less vibration.

What colors go well with #707dbb?

For interface work: #F5F6FA as the surface, #C8CDE5 for borders, #4B599B for secondary text, #8E6C3E as an accent and #293156 for hover and pressed states. For a palette, the analogous pair #70A2BB and #8870BB stays calm, while #BBAE70 is the loudest partner.

What is #707dbb in CMYK for printing?

cmyk(40%, 33%, 0%, 27%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #707dbb warm or cool?

Cool — it scores 89 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7E70BB; nudged cooler, #6E8DBD.

Which Tailwind color is closest to #707dbb?

The slate family — its 500 step is #64748b, ΔE2000 9.7 away. That is a visible difference, so define #707dbb as a custom token rather than reaching for the built-in.

How do I use #707dbb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#707dbb] or text-[#707dbb], 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 #707dbb with 50% opacity?

rgba(112, 125, 187, 0.5), or #707dbb80 in eight-digit hex. Over white that composites to #B8BEDD; over black, #383F5E.

Is #707dbb a web-safe color?

No. The nearest web-safe colour is #6666CC, ΔE2000 8.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #707dbb mean?
