How to use #4d817c

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
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • 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 #30504D
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 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 #4d817c 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.

#4d817c, answered

What color is #4d817c?

#4d817c is a dark soft cyan, closest to Teal (ΔE2000 6.5). It sits at 174° on the hue wheel with 25% saturation and 40% lightness, which reads as cool.

What is the RGB value of #4d817c?

rgb(77, 129, 124) — 77 red, 129 green and 124 blue out of 255, or 30.2% / 50.6% / 48.6% by channel.

What is #4d817c in HSL and HSV?

hsl(174, 25%, 40%) and hsv(174, 40%, 51%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #4d817c a light or a dark color?

It is a mid-tone. Relative luminance is 0.1873 and perceived brightness is 45%, so black text on it reaches 4.75:1.

Should I use black or white text on #4d817c?

Black. It scores 4.75:1 against #4d817c, versus 4.42:1 for white — AA at any size.

Is #4d817c accessible on a white background?

#4d817c on white scores 4.42:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #4B7E79 to reach 4.5:1, or #385E5A for 7:1.

What is the complementary color of #4d817c?

#814D52 sits directly opposite on the wheel. Softer options are the split-complements #814D6C and #81624D, which give the same contrast with far less vibration.

What colors go well with #4d817c?

For interface work: #F5F9F9 as the surface, #CCE0DE for borders, #56908A for secondary text, #85495E as an accent and #30504D for hover and pressed states. For a palette, the analogous pair #4D8162 and #4D6C81 stays calm, while #814D52 is the loudest partner.

What is #4d817c in CMYK for printing?

cmyk(40%, 0%, 4%, 49%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #4d817c warm or cool?

Cool — it scores 75 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #4D8169; nudged cooler, #4B7483.

Which Tailwind color is closest to #4d817c?

The neutral family — its 500 step is #737373, ΔE2000 17.2 away. That is a visible difference, so define #4d817c as a custom token rather than reaching for the built-in.

How do I use #4d817c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#4d817c] or text-[#4d817c], 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 #4d817c with 50% opacity?
