Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

  • 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
  • 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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. 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.

#754cfb, answered

What color is #754cfb?

#754cfb is a balanced electric blue, closest to Slate Blue (ΔE2000 6.9). It sits at 254° on the hue wheel with 96% saturation and 64% lightness, which reads as cool.

What is the RGB value of #754cfb?

rgb(117, 76, 251) — 117 red, 76 green and 251 blue out of 255, or 45.9% / 29.8% / 98.4% by channel.

What is #754cfb in HSL and HSV?

hsl(254, 96%, 64%) and hsv(254, 70%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #754cfb a light or a dark color?

It is a dark color. Relative luminance is 0.1592 and perceived brightness is 47%, so white text on it reaches 5.02:1.

Should I use black or white text on #754cfb?

White. It scores 5.02:1 against #754cfb, versus 4.18:1 for black — AA at any size.

Is #754cfb accessible on a white background?

#754cfb on white scores 5.02:1, which clears AA at every size but not AAA.

What is the complementary color of #754cfb?

#D2FB4C sits directly opposite on the wheel. Softer options are the split-complements #FBCD4C and #7AFB4C, which give the same contrast with far less vibration.

What colors go well with #754cfb?

For interface work: #F6F4FA as the surface, #CAC0ED for borders, #5D4B9B for secondary text, #CCC900 as an accent and #1F037D for hover and pressed states. For a palette, the analogous pair #4C7AFB and #CD4CFB stays calm, while #D2FB4C is the loudest partner.

What is #754cfb in CMYK for printing?

cmyk(53%, 70%, 0%, 2%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #754cfb warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B54CFB; nudged cooler, #4A62FD.

Which Tailwind color is closest to #754cfb?

The violet family — its 500 step is #8b5cf6, ΔE2000 5.4 away. That is a visible difference, so define #754cfb as a custom token rather than reaching for the built-in.

How do I use #754cfb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#754cfb] or text-[#754cfb], 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 #754cfb with 50% opacity?

rgba(117, 76, 251, 0.5), or #754cfb80 in eight-digit hex. Over white that composites to #BAA6FD; over black, #3B267E.

Is #754cfb a web-safe color?

No. The nearest web-safe colour is #6633FF, ΔE2000 5.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #754cfb 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 #754cfb?

The safest is same-hue elevation: linear-gradient(135deg, #A388FC, #754cfb 45%, #1F037D). For more colour, a short hue run to #F72EFA keeps it rich without turning muddy.
