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.

How to use #aeacfc

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #07047B
Safe as a 1px border on white
No — use #8784FB

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 lightness keeps it airy and approachable.

Worth knowing

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

#aeacfc, answered

What color is #aeacfc?

#aeacfc is a light electric blue, closest to Light Steel Blue (ΔE2000 9.6). It sits at 242° on the hue wheel with 93% saturation and 83% lightness, which reads as cool.

What is the RGB value of #aeacfc?

rgb(174, 172, 252) — 174 red, 172 green and 252 blue out of 255, or 68.2% / 67.5% / 98.8% by channel.

What is #aeacfc in HSL and HSV?

hsl(242, 93%, 83%) and hsv(242, 32%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aeacfc a light or a dark color?

It is a mid-tone. Relative luminance is 0.4553 and perceived brightness is 72%, so black text on it reaches 10.11:1.

Should I use black or white text on #aeacfc?

Black. It scores 10.11:1 against #aeacfc, versus 2.08:1 for white — AAA at any size.

Is #aeacfc accessible on a white background?

#aeacfc on white scores 2.08:1, which fails WCAG AA at every size. Darken it to #615DF9 to reach 4.5:1, or #3631F8 for 7:1.

What is the complementary color of #aeacfc?

#FAFCAC sits directly opposite on the wheel. Softer options are the split-complements #FCD6AC and #D2FCAC, which give the same contrast with far less vibration.

What colors go well with #aeacfc?

For interface work: #F4F4FA as the surface, #C1C0ED for borders, #4D4B9B for secondary text, #CA9C02 as an accent and #07047B for hover and pressed states. For a palette, the analogous pair #ACD2FC and #D6ACFC stays calm, while #FAFCAC is the loudest partner.

What is #aeacfc in CMYK for printing?

cmyk(31%, 32%, 0%, 1%). 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 #aeacfc 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 #CBACFC; nudged cooler, #ABC6FD.

Which Tailwind color is closest to #aeacfc?

The blue family — its 500 step is #3b82f6, ΔE2000 19.2 away. That is a visible difference, so define #aeacfc as a custom token rather than reaching for the built-in.

How do I use #aeacfc in Tailwind CSS?

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

rgba(174, 172, 252, 0.5), or #aeacfc80 in eight-digit hex. Over white that composites to #D7D6FE; over black, #57567E.

Is #aeacfc a web-safe color?

No. The nearest web-safe colour is #9999FF, ΔE2000 6 away. The palette only matters for legacy displays and some email clients now.

What does the color #aeacfc 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 #aeacfc?

The safest is same-hue elevation: linear-gradient(135deg, #E7E7FE, #aeacfc 45%, #07047B). For more colour, a short hue run to #E28EFB keeps it rich without turning muddy.
