How to use #61908f

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
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Small text on white — under 4.5:1
  • 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 #334C4C
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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

Worth knowing

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

Transparency

What each alpha value actually composites to. The top row is #61908f 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.

#61908f, answered

What color is #61908f?

#61908f is a balanced soft cyan, closest to Cadet Blue (ΔE2000 5). It sits at 179° on the hue wheel with 20% saturation and 47% lightness, which reads as cool.

What is the RGB value of #61908f?

rgb(97, 144, 143) — 97 red, 144 green and 143 blue out of 255, or 38% / 56.5% / 56.1% by channel.

What is #61908f in HSL and HSV?

hsl(179, 20%, 47%) and hsv(179, 33%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #61908f a light or a dark color?

It is a mid-tone. Relative luminance is 0.2447 and perceived brightness is 52%, so black text on it reaches 5.89:1.

Should I use black or white text on #61908f?

Black. It scores 5.89:1 against #61908f, versus 3.56:1 for white — AA at any size.

Is #61908f accessible on a white background?

#61908f on white scores 3.56:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #557E7D to reach 4.5:1, or #3E5C5C for 7:1.

What is the complementary color of #61908f?

#906162 sits directly opposite on the wheel. Softer options are the split-complements #90617A and #907861, which give the same contrast with far less vibration.

What colors go well with #61908f?

For interface work: #F6F9F9 as the surface, #CEDEDE for borders, #5C8988 for secondary text, #955C6C as an accent and #334C4C for hover and pressed states. For a palette, the analogous pair #619078 and #617A90 stays calm, while #906162 is the loudest partner.

What is #61908f in CMYK for printing?

cmyk(33%, 0%, 1%, 44%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #61908f warm or cool?

Cool — it scores 71 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #61907E; nudged cooler, #5F8193.

Which Tailwind color is closest to #61908f?

The teal family — its 500 step is #14b8a6, ΔE2000 15.3 away. That is a visible difference, so define #61908f as a custom token rather than reaching for the built-in.

How do I use #61908f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#61908f] or text-[#61908f], 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 #61908f with 50% opacity?
