How to use #29393d

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

Works well for
  • Body text and links on white
  • Charts, tags and secondary surfaces
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • 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

Safe as a fill behind white type

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 #29393d 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.

#29393d, answered

What color is #29393d?

#29393d is a deep soft cyan, closest to Dark Slate Gray (ΔE2000 8.9). It sits at 192° on the hue wheel with 20% saturation and 20% lightness, which reads as cool.

What is the RGB value of #29393d?

rgb(41, 57, 61) — 41 red, 57 green and 61 blue out of 255, or 16.1% / 22.4% / 23.9% by channel.

What is #29393d in HSL and HSV?

hsl(192, 20%, 20%) and hsv(192, 33%, 24%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #29393d a light or a dark color?

It is a dark color. Relative luminance is 0.0373 and perceived brightness is 21%, so white text on it reaches 12.02:1.

Should I use black or white text on #29393d?

White. It scores 12.02:1 against #29393d, versus 1.75:1 for black — AAA at any size.

Is #29393d accessible on a white background?

#29393d on white scores 12.02:1, which clears AAA at every size.

What is the complementary color of #29393d?

#3D2D29 sits directly opposite on the wheel. Softer options are the split-complements #3D292F and #3D3729, which give the same contrast with far less vibration.

What colors go well with #29393d?

For interface work: #F6F8F9 as the surface, #CEDBDE for borders, #5C8089 for secondary text, #3F2728 as an accent and #33474C for hover and pressed states. For a palette, the analogous pair #293D37 and #292F3D stays calm, while #3D2D29 is the loudest partner.

What is #29393d in CMYK for printing?

cmyk(33%, 7%, 0%, 76%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #29393d 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 #293D3A; nudged cooler, #28333E.

Which Tailwind color is closest to #29393d?

The gray family — its 500 step is #6b7280, ΔE2000 22.2 away. That is a visible difference, so define #29393d as a custom token rather than reaching for the built-in.

How do I use #29393d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#29393d] or text-[#29393d], 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 #29393d with 50% opacity?

rgba(41, 57, 61, 0.5), or #29393d80 in eight-digit hex. Over white that composites to #949C9E; over black, #151D1F.

Is #29393d a web-safe color?

No. The nearest web-safe colour is #333333, ΔE2000 7.7 away. The palette only matters for legacy displays and some email clients now.
