How to use #195050

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

Works well for
  • Body text and links on white
  • 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
  • Text on black or near-black surfaces
  • 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

Safe as a fill behind white type

Safe as a 1px border on white

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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 #195050 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.

#195050, answered

What color is #195050?

#195050 is a deep vivid cyan, closest to Dark Slate Gray (ΔE2000 4.3). It sits at 180° on the hue wheel with 52% saturation and 21% lightness, which reads as cool.

What is the RGB value of #195050?

rgb(25, 80, 80) — 25 red, 80 green and 80 blue out of 255, or 9.8% / 31.4% / 31.4% by channel.

What is #195050 in HSL and HSV?

hsl(180, 52%, 21%) and hsv(180, 69%, 31%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #195050 a light or a dark color?

It is a dark color. Relative luminance is 0.0652 and perceived brightness is 27%, so white text on it reaches 9.11:1.

Should I use black or white text on #195050?

White. It scores 9.11:1 against #195050, versus 2.30:1 for black — AAA at any size.

Is #195050 accessible on a white background?

#195050 on white scores 9.11:1, which clears AAA at every size.

What is the complementary color of #195050?

#501919 sits directly opposite on the wheel. Softer options are the split-complements #501935 and #503519, which give the same contrast with far less vibration.

What colors go well with #195050?

For interface work: #F4FAFA as the surface, #C1ECEC for borders, #4B9B9B for secondary text, #521726 as an accent and #1E6161 for hover and pressed states. For a palette, the analogous pair #195035 and #193550 stays calm, while #501919 is the loudest partner.

What is #195050 in CMYK for printing?

cmyk(69%, 0%, 0%, 69%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #195050 warm or cool?

Cool — it scores 88 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #19503C; nudged cooler, #183C51.

Which Tailwind color is closest to #195050?

The neutral family — its 500 step is #737373, ΔE2000 22.7 away. That is a visible difference, so define #195050 as a custom token rather than reaching for the built-in.

How do I use #195050 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#195050] or text-[#195050], 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 #195050 with 50% opacity?

rgba(25, 80, 80, 0.5), or #19505080 in eight-digit hex. Over white that composites to #8CA8A8; over black, #0D2828.

Is #195050 a web-safe color?

No. The nearest web-safe colour is #006666, ΔE2000 7.7 away. The palette only matters for legacy displays and some email clients now.
