}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 #45A64C 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: #4eb656 as text on that neutral, and that neutral as text on #4eb656.

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. #4eb656 is pinned to step 600; 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.

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

#4eb656 is a balanced soft green, closest to Medium Sea Green (ΔE2000 6.1). It sits at 125° on the hue wheel with 42% saturation and 51% lightness, which reads as cool.
What is the RGB value of #4eb656?
rgb(78, 182, 86) — 78 red, 182 green and 86 blue out of 255, or 30.6% / 71.4% / 33.7% by channel.
What is #4eb656 in HSL and HSV?
hsl(125, 42%, 51%) and hsv(125, 57%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #4eb656 a light or a dark color?
It is a mid-tone. Relative luminance is 0.3575 and perceived brightness is 58%, so black text on it reaches 8.15:1.

Black. It scores 8.15:1 against #4eb656, versus 2.58:1 for white — AAA at any size.
Is #4eb656 accessible on a white background?
#4eb656 on white scores 2.58:1, which fails WCAG AA at every size. Darken it to #37863D to reach 4.5:1, or #2A652E for 7:1.
What is the complementary color of #4eb656?
#B64EAE sits directly opposite on the wheel. Softer options are the split-complements #8A4EB6 and #B64E7A, which give the same contrast with far less vibration.
What colors go well with #4eb656?
For interface work: #F4FAF5 as the surface, #C5E7C8 for borders, #4B9B51 for secondary text, #A749BB as an accent and #255A29 for hover and pressed states. For a palette, the analogous pair #7AB64E and #4EB68A stays calm, while #B64EAE is the loudest partner.
What is #4eb656 in CMYK for printing?
cmyk(57%, 0%, 53%, 29%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.
Is #4eb656 warm or cool?
Cool — it scores 64 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #6CB64E; nudged cooler, #4CB97C.
Which Tailwind color is closest to #4eb656?
The green family — its 500 step is #22c55e, ΔE2000 4.7 away. That is a visible difference, so define #4eb656 as a custom token rather than reaching for the built-in.
How do I use #4eb656 in Tailwind CSS?
Inline it as an arbitrary value with bg-[#4eb656] or text-[#4eb656], 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 #4eb656 with 50% opacity?
rgba(78, 182, 86, 0.5), or #4eb65680 in eight-digit hex. Over white that composites to #A7DBAB; over black, #275B2B.
Is #4eb656 a web-safe color?
No. The nearest web-safe colour is #66CC66, ΔE2000 6.1 away. The palette only matters for legacy displays and some email clients now.
What does the color #4eb656 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 moderate chroma the association is present but not shouted.
What gradient works with #4eb656?
The safest is same-hue elevation: linear-gradient(135deg, #79C87F, #4eb656 45%, #255A29). For more colour, a short hue run to #43A292 keeps it rich without turning muddy.
