At a glance
Every number on this page in one read: what #ace58b is made of, how bright it looks, and which way it leans.
Left edge is grey, right edge is full chroma; top is white, bottom is black. The dot is #ace58b.
Reads neutral. Warm and cool siblings keep the same lightness, so you can swap one in without redoing your contrast maths.
Green carries most of what the eye calls brightness — that is why WCAG weights it 0.7152.

}Best text color
Only one of black and white can be right. This is the one, with the number that proves it.
Make it accessible
A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.
Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #53A325 is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).
Accessibility — WCAG contrast
Contrast is symmetric, so each row covers both directions: #ace58b as text on that neutral, and that neutral as text on #ace58b.

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.
Color scale — 50 to 950
A Tailwind-shaped ramp built around this exact hex. #ace58b is pinned to step 400; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
The same eleven steps expressed in OKLCH, where equal lightness numbers actually look equally spaced. HSL ramps go muddy in the yellows and washed out in the blues; this one does not. Modern browsers render it natively — the hex ramp above is the fallback.

Not a palette — a role sheet. Each swatch answers one question you will hit while building the component.
Surface, border, heading and body all derive from this one hue, so the screen stays coherent without a second palette.
Lightness flips, hue holds. The accent stays the anchor in both themes.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
Green means go, well, and grown. It carries finance, sustainability and health with almost no explanation needed.
This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.
Red/green pairs are the most common colour-blindness failure — never let the two carry meaning alone.

#ace58b, answered
What color is #ace58b?
#ace58b is a light vivid green, closest to Light Green (ΔE2000 5). It sits at 98° on the hue wheel with 63% saturation and 72% lightness, which reads as neutral.
What is the RGB value of #ace58b?
rgb(172, 229, 139) — 172 red, 229 green and 139 blue out of 255, or 67.5% / 89.8% / 54.5% by channel.
What is #ace58b in HSL and HSV?
hsl(98, 63%, 72%) and hsv(98, 39%, 90%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #ace58b a light or a dark color?
It is a light color. Relative luminance is 0.6667 and perceived brightness is 80%, so black text on it reaches 14.33:1.
Should I use black or white text on #ace58b?
Black. It scores 14.33:1 against #ace58b, versus 1.46:1 for white — AAA at any size.
Is #ace58b accessible on a white background?
#ace58b on white scores 1.46:1, which fails WCAG AA at every size. Darken it to #42821D to reach 4.5:1, or #316116 for 7:1.
What is the complementary color of #ace58b?
#C48BE5 sits directly opposite on the wheel. Softer options are the split-complements #978BE5 and #E58BD9, which give the same contrast with far less vibration.
What colors go well with #ace58b?
For interface work: #F7FAF4 as the surface, #D0EDC0 for borders, #689B4B for secondary text, #5621AB as an accent and #356817 for hover and pressed states. For a palette, the analogous pair #D9E58B and #8BE597 stays calm, while #C48BE5 is the loudest partner.
What is #ace58b in CMYK for printing?
cmyk(25%, 0%, 39%, 10%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.
Is #ace58b warm or cool?
Neutral — it scores 53 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CDE58B; nudged cooler, #8AE68A.
Which Tailwind color is closest to #ace58b?
The lime family — its 500 step is #84cc16, ΔE2000 11.9 away. That is a visible difference, so define #ace58b as a custom token rather than reaching for the built-in.
How do I use #ace58b in Tailwind CSS?
Inline it as an arbitrary value with bg-[#ace58b] or text-[#ace58b], 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 #ace58b with 50% opacity?
rgba(172, 229, 139, 0.5), or #ace58b80 in eight-digit hex. Over white that composites to #D6F2C5; over black, #567346.
Is #ace58b a web-safe color?
No. The nearest web-safe colour is #99CC99, ΔE2000 9.2 away. The palette only matters for legacy displays and some email clients now.
What does the color #ace58b 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 #ace58b?
The safest is same-hue elevation: linear-gradient(135deg, #D0F0BD, #ace58b 45%, #356817). For more colour, a short hue run to #72DF9C keeps it rich without turning muddy.
