Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #0ace7c

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

Works well for
  • Text and icons on dark surfaces
  • 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 of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • Status meaning — pair it with an icon or label, never colour alone
  • 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 #067A49
Safe as a 1px border on white
No — use #08A765

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

safegrowingnaturalpermissive

Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

Worth knowing

Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

Transparency

What each alpha value actually composites to. The top row is #0ace7c 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.

#0ace7c, answered

What color is #0ace7c?

#0ace7c is a dark electric green, closest to Medium Sea Green (ΔE2000 7.3). It sits at 155° on the hue wheel with 91% saturation and 42% lightness, which reads as cool.

What is the RGB value of #0ace7c?

rgb(10, 206, 124) — 10 red, 206 green and 124 blue out of 255, or 3.9% / 80.8% / 48.6% by channel.

What is #0ace7c in HSL and HSV?

hsl(155, 91%, 42%) and hsv(155, 95%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #0ace7c a light or a dark color?

It is a mid-tone. Relative luminance is 0.4566 and perceived brightness is 64%, so black text on it reaches 10.13:1.

Should I use black or white text on #0ace7c?

Black. It scores 10.13:1 against #0ace7c, versus 2.07:1 for white — AAA at any size.

Is #0ace7c accessible on a white background?

#0ace7c on white scores 2.07:1, which fails WCAG AA at every size. Darken it to #068550 to reach 4.5:1, or #05633C for 7:1.

What is the complementary color of #0ace7c?

#CE0A5C sits directly opposite on the wheel. Softer options are the split-complements #CE0ABE and #CE1A0A, which give the same contrast with far less vibration.

What colors go well with #0ace7c?

For interface work: #F4FAF8 as the surface, #C0EDDA for borders, #4B9B79 for secondary text, #D3068F as an accent and #067A49 for hover and pressed states. For a palette, the analogous pair #0ACE1A and #0ABECE stays calm, while #CE0A5C is the loudest partner.

What is #0ace7c in CMYK for printing?

cmyk(95%, 0%, 40%, 19%). This is a screen-to-ink approximation — a color this saturated sits outside most CMYK gamuts and will print duller than it looks here.

Is #0ace7c warm or cool?

Cool — it scores 77 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #0ACE34; nudged cooler, #08D0C6.

Which Tailwind color is closest to #0ace7c?

The green family — its 500 step is #22c55e, ΔE2000 4.7 away. That is a visible difference, so define #0ace7c as a custom token rather than reaching for the built-in.

How do I use #0ace7c in Tailwind CSS?

Inline it as an arbitrary value with bg-[#0ace7c] or text-[#0ace7c], 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 #0ace7c with 50% opacity?

rgba(10, 206, 124, 0.5), or #0ace7c80 in eight-digit hex. Over white that composites to #85E7BE; over black, #05673E.

Is #0ace7c a web-safe color?

No. The nearest web-safe colour is #00CC66, ΔE2000 3.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #0ace7c mean?

As a green, it reads safe, growing, natural. Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #0ace7c?
