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 #aebbc5

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #35414A
Safe as a 1px border on white
No — use #8195A5

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 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.

What each alpha value actually composites to. The top row is #aebbc5 over white; the bottom row is the same alpha over a checkerboard, so you can see what survives on a photo or a video.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#aebbc5, answered

What color is #aebbc5?

#aebbc5 is a light soft blue, closest to Light Steel Blue (ΔE2000 6.5). It sits at 206° on the hue wheel with 17% saturation and 73% lightness, which reads as cool.

What is the RGB value of #aebbc5?

rgb(174, 187, 197) — 174 red, 187 green and 197 blue out of 255, or 68.2% / 73.3% / 77.3% by channel.

What is #aebbc5 in HSL and HSV?

hsl(206, 17%, 73%) and hsv(206, 12%, 77%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aebbc5 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4857 and perceived brightness is 72%, so black text on it reaches 10.71:1.

Should I use black or white text on #aebbc5?

Black. It scores 10.71:1 against #aebbc5, versus 1.96:1 for white — AAA at any size.

Is #aebbc5 accessible on a white background?

#aebbc5 on white scores 1.96:1, which fails WCAG AA at every size. Darken it to #617788 to reach 4.5:1, or #4A5A67 for 7:1.

What is the complementary color of #aebbc5?

#C5B8AE sits directly opposite on the wheel. Softer options are the split-complements #C5AEAF and #C5C3AE, which give the same contrast with far less vibration.

What colors go well with #aebbc5?

For interface work: #F6F8F9 as the surface, #CFD7DD for borders, #607586 for secondary text, #7B5851 as an accent and #35414A for hover and pressed states. For a palette, the analogous pair #AEC5C3 and #AEAFC5 stays calm, while #C5B8AE is the loudest partner.

What is #aebbc5 in CMYK for printing?

cmyk(12%, 5%, 0%, 23%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aebbc5 warm or cool?

Cool — it scores 73 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AEB2C5; nudged cooler, #9DACBC.

Which Tailwind color is closest to #aebbc5?

The cyan family — its 500 step is #06b6d4, ΔE2000 18.4 away. That is a visible difference, so define #aebbc5 as a custom token rather than reaching for the built-in.

How do I use #aebbc5 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aebbc5] or text-[#aebbc5], 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 #aebbc5 with 50% opacity?

rgba(174, 187, 197, 0.5), or #aebbc580 in eight-digit hex. Over white that composites to #D7DDE2; over black, #575E63.

Is #aebbc5 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 13.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #aebbc5 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 moderate chroma the association is present but not shouted.

What gradient works with #aebbc5?

The safest is same-hue elevation: linear-gradient(135deg, #D2D9DE, #aebbc5 45%, #35414A). For more colour, a short hue run to #A19CB8 keeps it rich without turning muddy.
