How to use #768cd3

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
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • 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 #1F2E61
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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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.

#768cd3, answered

What color is #768cd3?

#768cd3 is a balanced vivid blue, closest to Cornflower Blue (ΔE2000 6.2). It sits at 226° on the hue wheel with 51% saturation and 65% lightness, which reads as cool.

What is the RGB value of #768cd3?

rgb(118, 140, 211) — 118 red, 140 green and 211 blue out of 255, or 46.3% / 54.9% / 82.7% by channel.

What is #768cd3 in HSL and HSV?

hsl(226, 51%, 65%) and hsv(226, 44%, 83%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #768cd3 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2731 and perceived brightness is 56%, so black text on it reaches 6.46:1.

Should I use black or white text on #768cd3?

Black. It scores 6.46:1 against #768cd3, versus 3.25:1 for white — AA at any size.

Is #768cd3 accessible on a white background?

#768cd3 on white scores 3.25:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #5772C9 to reach 4.5:1, or #3753AC for 7:1.

What is the complementary color of #768cd3?

#D3BD76 sits directly opposite on the wheel. Softer options are the split-complements #D38E76 and #BAD376, which give the same contrast with far less vibration.

What colors go well with #768cd3?

For interface work: #F4F6FA as the surface, #C1CBEB for borders, #4B5E9B for secondary text, #9F682D as an accent and #1F2E61 for hover and pressed states. For a palette, the analogous pair #76BAD3 and #8E76D3 stays calm, while #D3BD76 is the loudest partner.

What is #768cd3 in CMYK for printing?

cmyk(44%, 34%, 0%, 17%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #768cd3 warm or cool?

Cool — it scores 91 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #8276D3; nudged cooler, #749AD5.

Which Tailwind color is closest to #768cd3?

The blue family — its 500 step is #3b82f6, ΔE2000 8.4 away. That is a visible difference, so define #768cd3 as a custom token rather than reaching for the built-in.

How do I use #768cd3 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#768cd3] or text-[#768cd3], 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 #768cd3 with 50% opacity?

rgba(118, 140, 211, 0.5), or #768cd380 in eight-digit hex. Over white that composites to #BBC6E9; over black, #3B466A.

Is #768cd3 a web-safe color?

No. The nearest web-safe colour is #6699CC, ΔE2000 7.6 away. The palette only matters for legacy displays and some email clients now.
