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

How to use #97fc2d

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #417E02
Safe as a 1px border on white
No — use #57A702

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 mid lightness keeps it versatile in both themes.

Worth knowing

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

#97fc2d, answered

What color is #97fc2d?

#97fc2d is a balanced electric green, closest to Chartreuse (ΔE2000 2.2). It sits at 89° on the hue wheel with 97% saturation and 58% lightness, which reads as neutral.

What is the RGB value of #97fc2d?

rgb(151, 252, 45) — 151 red, 252 green and 45 blue out of 255, or 59.2% / 98.8% / 17.6% by channel.

What is #97fc2d in HSL and HSV?

hsl(89, 97%, 58%) and hsv(89, 82%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #97fc2d a light or a dark color?

It is a light color. Relative luminance is 0.7639 and perceived brightness is 83%, so black text on it reaches 16.28:1.

Should I use black or white text on #97fc2d?

Black. It scores 16.28:1 against #97fc2d, versus 1.29:1 for white — AAA at any size.

Is #97fc2d accessible on a white background?

#97fc2d on white scores 1.29:1, which fails WCAG AA at every size. Darken it to #448402 to reach 4.5:1, or #326101 for 7:1.

What is the complementary color of #97fc2d?

#922DFC sits directly opposite on the wheel. Softer options are the split-complements #2D2FFC and #FA2DFC, which give the same contrast with far less vibration.

What colors go well with #97fc2d?

For interface work: #F7FAF4 as the surface, #D7EDC0 for borders, #749B4B for secondary text, #5D2AFF as an accent and #417E02 for hover and pressed states. For a palette, the analogous pair #FCFA2D and #2FFC2D stays calm, while #922DFC is the loudest partner.

What is #97fc2d in CMYK for printing?

cmyk(40%, 0%, 82%, 1%). 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 #97fc2d warm or cool?

Neutral — it scores 49 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #E3FC2D; nudged cooler, #49FE2B.

Which Tailwind color is closest to #97fc2d?

The lime family — its 500 step is #84cc16, ΔE2000 10.7 away. That is a visible difference, so define #97fc2d as a custom token rather than reaching for the built-in.

How do I use #97fc2d in Tailwind CSS?

Inline it as an arbitrary value with bg-[#97fc2d] or text-[#97fc2d], 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 #97fc2d with 50% opacity?

rgba(151, 252, 45, 0.5), or #97fc2d80 in eight-digit hex. Over white that composites to #CBFE96; over black, #4C7E17.

Is #97fc2d a web-safe color?

No. The nearest web-safe colour is #99FF33, ΔE2000 0.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #97fc2d mean?
