How to use #089969

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

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • Black 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #067953
Safe as a 1px border on white
Yes

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

Worth knowing

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

What each alpha value actually composites to. The top row is #089969 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.

#089969, answered

What color is #089969?

#089969 is a dark electric cyan, closest to Sea Green (ΔE2000 5.5). It sits at 160° on the hue wheel with 90% saturation and 32% lightness, which reads as cool.

What is the RGB value of #089969?

rgb(8, 153, 105) — 8 red, 153 green and 105 blue out of 255, or 3.1% / 60% / 41.2% by channel.

What is #089969 in HSL and HSV?

hsl(160, 90%, 32%) and hsv(160, 95%, 60%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #089969 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2385 and perceived brightness is 48%, so black text on it reaches 5.77:1.

Should I use black or white text on #089969?

Black. It scores 5.77:1 against #089969, versus 3.64:1 for white — AA at any size.

Is #089969 accessible on a white background?

#089969 on white scores 3.64:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #07865C to reach 4.5:1, or #056444 for 7:1.

What is the complementary color of #089969?

#990838 sits directly opposite on the wheel. Softer options are the split-complements #990881 and #992008, which give the same contrast with far less vibration.

What colors go well with #089969?

For interface work: #F4FAF8 as the surface, #C0EDDE for borders, #4B9B80 for secondary text, #9C055D as an accent and #067953 for hover and pressed states. For a palette, the analogous pair #089920 and #088199 stays calm, while #990838 is the loudest partner.

What is #089969 in CMYK for printing?

cmyk(95%, 0%, 31%, 40%). 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 #089969 warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #089934; nudged cooler, #06969B.

Which Tailwind color is closest to #089969?

The emerald family — its 500 step is #10b981, ΔE2000 9.6 away. That is a visible difference, so define #089969 as a custom token rather than reaching for the built-in.

How do I use #089969 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#089969] or text-[#089969], 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 #089969 with 50% opacity?
