How to use #5ba592

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

Works well for
  • 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
  • Text of any size on white — fails WCAG AA
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #2D5249
Safe as a 1px border on white
No — use #59A28F

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 #5ba592 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.

#5ba592, answered

What color is #5ba592?

#5ba592 is a balanced soft cyan, closest to Light Sea Green (ΔE2000 7.5). It sits at 165° on the hue wheel with 29% saturation and 50% lightness, which reads as cool.

What is the RGB value of #5ba592?

rgb(91, 165, 146) — 91 red, 165 green and 146 blue out of 255, or 35.7% / 64.7% / 57.3% by channel.

What is #5ba592 in HSL and HSV?

hsl(165, 29%, 50%) and hsv(165, 45%, 65%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #5ba592 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3121 and perceived brightness is 57%, so black text on it reaches 7.24:1.

Should I use black or white text on #5ba592?

Black. It scores 7.24:1 against #5ba592, versus 2.90:1 for white — AAA at any size.

Is #5ba592 accessible on a white background?

#5ba592 on white scores 2.90:1, which fails WCAG AA at every size. Darken it to #478172 to reach 4.5:1, or #356055 for 7:1.

What is the complementary color of #5ba592?

#A55B6E sits directly opposite on the wheel. Softer options are the split-complements #A55B93 and #A56D5B, which give the same contrast with far less vibration.

What colors go well with #5ba592?

For interface work: #F5FAF8 as the surface, #CAE2DC for borders, #519483 for secondary text, #AA5681 as an accent and #2D5249 for hover and pressed states. For a palette, the analogous pair #5BA56D and #5B93A5 stays calm, while #A55B6E is the loudest partner.

What is #5ba592 in CMYK for printing?

cmyk(45%, 0%, 12%, 35%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #5ba592 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 #5BA577; nudged cooler, #599FA8.

Which Tailwind color is closest to #5ba592?

The teal family — its 500 step is #14b8a6, ΔE2000 7.5 away. That is a visible difference, so define #5ba592 as a custom token rather than reaching for the built-in.

How do I use #5ba592 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#5ba592] or text-[#5ba592], 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 #5ba592 with 50% opacity?

rgba(91, 165, 146, 0.5), or #5ba59280 in eight-digit hex. Over white that composites to #ADD2C9; over black, #2E5349.

Is #5ba592 a web-safe color?

No. The nearest web-safe colour is #669999, ΔE2000 8.9 away. The palette only matters for legacy displays and some email clients now.
