  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions
  • Pairing with a same-lightness hue — edges vibrate

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.

#6047df, answered

What color is #6047df?

#6047df is a balanced vivid blue, closest to Slate Blue (ΔE2000 5.7). It sits at 250° on the hue wheel with 70% saturation and 58% lightness, which reads as cool.

What is the RGB value of #6047df?

rgb(96, 71, 223) — 96 red, 71 green and 223 blue out of 255, or 37.6% / 27.8% / 87.5% by channel.

What is #6047df in HSL and HSV?

hsl(250, 70%, 58%) and hsv(250, 68%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6047df a light or a dark color?

It is a dark color. Relative luminance is 0.1232 and perceived brightness is 42%, so white text on it reaches 6.06:1.

Should I use black or white text on #6047df?

White. It scores 6.06:1 against #6047df, versus 3.46:1 for black — AA at any size.

Is #6047df accessible on a white background?

#6047df on white scores 6.06:1, which clears AA at every size but not AAA.

What is the complementary color of #6047df?

#C6DF47 sits directly opposite on the wheel. Softer options are the split-complements #DFAC47 and #7ADF47, which give the same contrast with far less vibration.

What colors go well with #6047df?

For interface work: #F5F4FA as the surface, #C7C0ED for borders, #584B9B for secondary text, #B2A61A as an accent and #22136D for hover and pressed states. For a palette, the analogous pair #477ADF and #AC47DF stays calm, while #C6DF47 is the loudest partner.

What is #6047df in CMYK for printing?

cmyk(57%, 68%, 0%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #6047df warm or cool?

Cool — it scores 78 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9847DF; nudged cooler, #4564E1.

Which Tailwind color is closest to #6047df?

The indigo family — its 500 step is #6366f1, ΔE2000 9.4 away. That is a visible difference, so define #6047df as a custom token rather than reaching for the built-in.

How do I use #6047df in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6047df] or text-[#6047df], 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 #6047df with 50% opacity?

rgba(96, 71, 223, 0.5), or #6047df80 in eight-digit hex. Over white that composites to #B0A3EF; over black, #302470.

Is #6047df a web-safe color?

No. The nearest web-safe colour is #6633CC, ΔE2000 5.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #6047df mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #6047df?

The safest is same-hue elevation: linear-gradient(135deg, #8D7BE8, #6047df 45%, #22136D). For more colour, a short hue run to #CC2DDA keeps it rich without turning muddy.
