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.

Color scale — 50 to 950

How to use #abbada

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 #273758
Safe as a 1px border on white
No — use #7D94C6

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.

Transparency

What each alpha value actually composites to. The top row is #abbada 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.

#abbada, answered

What color is #abbada?

#abbada is a light soft blue, closest to Light Steel Blue (ΔE2000 4.1). It sits at 221° on the hue wheel with 39% saturation and 76% lightness, which reads as cool.

What is the RGB value of #abbada?

rgb(171, 186, 218) — 171 red, 186 green and 218 blue out of 255, or 67.1% / 72.9% / 85.5% by channel.

What is #abbada in HSL and HSV?

hsl(221, 39%, 76%) and hsv(221, 22%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #abbada a light or a dark color?

It is a mid-tone. Relative luminance is 0.4884 and perceived brightness is 73%, so black text on it reaches 10.77:1.

Should I use black or white text on #abbada?

Black. It scores 10.77:1 against #abbada, versus 1.95:1 for white — AAA at any size.

Is #abbada accessible on a white background?

#abbada on white scores 1.95:1, which fails WCAG AA at every size. Darken it to #5674B5 to reach 4.5:1, or #3D568B for 7:1.

What is the complementary color of #abbada?

#DACBAB sits directly opposite on the wheel. Softer options are the split-complements #DAB4AB and #D1DAAB, which give the same contrast with far less vibration.

What colors go well with #abbada?

For interface work: #F4F6FA as the surface, #C6D0E6 for borders, #4B649B for secondary text, #91603B as an accent and #273758 for hover and pressed states. For a palette, the analogous pair #ABD1DA and #B4ABDA stays calm, while #DACBAB is the loudest partner.

What is #abbada in CMYK for printing?

cmyk(22%, 15%, 0%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #abbada warm or cool?

Cool — it scores 94 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ADABDA; nudged cooler, #AAC0DB.

Which Tailwind color is closest to #abbada?

The sky family — its 500 step is #0ea5e9, ΔE2000 19.3 away. That is a visible difference, so define #abbada as a custom token rather than reaching for the built-in.

How do I use #abbada in Tailwind CSS?

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

rgba(171, 186, 218, 0.5), or #abbada80 in eight-digit hex. Over white that composites to #D5DDED; over black, #565D6D.

Is #abbada a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 18.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #abbada 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 #abbada?

The safest is same-hue elevation: linear-gradient(135deg, #D6DDED, #abbada 45%, #273758). For more colour, a short hue run to #AF96D1 keeps it rich without turning muddy.
