Works well for
  • Body text and links on white
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Black text placed on it
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate

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 low lightness adds weight and formality.

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 #45816f 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.

#45816f, answered

What color is #45816f?

#45816f is a dark soft cyan, closest to Teal (ΔE2000 8.8). It sits at 162° on the hue wheel with 30% saturation and 39% lightness, which reads as cool.

What is the RGB value of #45816f?

rgb(69, 129, 111) — 69 red, 129 green and 111 blue out of 255, or 27.1% / 50.6% / 43.5% by channel.

What is #45816f in HSL and HSV?

hsl(162, 30%, 39%) and hsv(162, 47%, 51%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #45816f a light or a dark color?

It is a mid-tone. Relative luminance is 0.1811 and perceived brightness is 44%, so black text on it reaches 4.62:1.

Should I use black or white text on #45816f?

Black. It scores 4.62:1 against #45816f, versus 4.54:1 for white — AA at any size.

Is #45816f accessible on a white background?

#45816f on white scores 4.54:1, which clears AA at every size but not AAA.

What is the complementary color of #45816f?

#814557 sits directly opposite on the wheel. Softer options are the split-complements #814575 and #815145, which give the same contrast with far less vibration.

What colors go well with #45816f?

For interface work: #F5FAF8 as the surface, #CAE3DB for borders, #509681 for secondary text, #854166 as an accent and #2C5347 for hover and pressed states. For a palette, the analogous pair #458151 and #457581 stays calm, while #814557 is the loudest partner.

What is #45816f in CMYK for printing?

cmyk(47%, 0%, 14%, 49%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #45816f warm or cool?

Cool — it scores 76 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #458159; nudged cooler, #437F83.

Which Tailwind color is closest to #45816f?

The teal family — its 500 step is #14b8a6, ΔE2000 18 away. That is a visible difference, so define #45816f as a custom token rather than reaching for the built-in.

How do I use #45816f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#45816f] or text-[#45816f], 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 #45816f with 50% opacity?

rgba(69, 129, 111, 0.5), or #45816f80 in eight-digit hex. Over white that composites to #A2C0B7; over black, #234138.

Is #45816f a web-safe color?
