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 #aaccc6

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
  • Thin strokes and 1px borders — they disappear on light UI
  • 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 #30504A
Safe as a 1px border on white
No — use #61A095

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

cleantechnicalfreshclinical

Cyan reads as water, air and infrastructure: cool, hygienic, engineered.

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

At high lightness it disappears into white surfaces and thin strokes vanish entirely.

#aaccc6, answered

What color is #aaccc6?

#aaccc6 is a light soft cyan, closest to Powder Blue (ΔE2000 7.1). It sits at 169° on the hue wheel with 25% saturation and 73% lightness, which reads as cool.

What is the RGB value of #aaccc6?

rgb(170, 204, 198) — 170 red, 204 green and 198 blue out of 255, or 66.7% / 80% / 77.6% by channel.

What is #aaccc6 in HSL and HSV?

hsl(169, 25%, 73%) and hsv(169, 17%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aaccc6 a light or a dark color?

It is a light color. Relative luminance is 0.5581 and perceived brightness is 76%, so black text on it reaches 12.16:1.

Should I use black or white text on #aaccc6?

Black. It scores 12.16:1 against #aaccc6, versus 1.73:1 for white — AAA at any size.

Is #aaccc6 accessible on a white background?

#aaccc6 on white scores 1.73:1, which fails WCAG AA at every size. Darken it to #4D8077 to reach 4.5:1, or #385D57 for 7:1.

What is the complementary color of #aaccc6?

#CCAAB0 sits directly opposite on the wheel. Softer options are the split-complements #CCAAC1 and #CCB5AA, which give the same contrast with far less vibration.

What colors go well with #aaccc6?

For interface work: #F5F9F9 as the surface, #CCE0DD for borders, #568F85 for secondary text, #844862 as an accent and #30504A for hover and pressed states. For a palette, the analogous pair #AACCB5 and #AAC1CC stays calm, while #CCAAB0 is the loudest partner.

What is #aaccc6 in CMYK for printing?

cmyk(17%, 0%, 3%, 20%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aaccc6 warm or cool?

Cool — it scores 74 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AACCB9; nudged cooler, #A9C6CD.

Which Tailwind color is closest to #aaccc6?

The teal family — its 500 step is #14b8a6, ΔE2000 16.5 away. That is a visible difference, so define #aaccc6 as a custom token rather than reaching for the built-in.

How do I use #aaccc6 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aaccc6] or text-[#aaccc6], 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 #aaccc6 with 50% opacity?

rgba(170, 204, 198, 0.5), or #aaccc680 in eight-digit hex. Over white that composites to #D5E6E3; over black, #556663.

Is #aaccc6 a web-safe color?

No. The nearest web-safe colour is #99CCCC, ΔE2000 4.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #aaccc6 mean?

As a cyan, it reads clean, technical, fresh. Cyan reads as water, air and infrastructure: cool, hygienic, engineered. At this moderate chroma the association is present but not shouted.

What gradient works with #aaccc6?

The safest is same-hue elevation: linear-gradient(135deg, #D0E3E0, #aaccc6 45%, #30504A). For more colour, a short hue run to #97A9C0 keeps it rich without turning muddy.
