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 #dbf839

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
  • 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 #697B04
Safe as a 1px border on white
No — use #869D06

Meaning and mood

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

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

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

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

Transparency

What each alpha value actually composites to. The top row is #dbf839 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.

#dbf839, answered

What color is #dbf839?

#dbf839 is a balanced electric yellow, closest to Yellow (ΔE2000 7.1). It sits at 69° on the hue wheel with 93% saturation and 60% lightness, which reads as warm.

What is the RGB value of #dbf839?

rgb(219, 248, 57) — 219 red, 248 green and 57 blue out of 255, or 85.9% / 97.3% / 22.4% by channel.

What is #dbf839 in HSL and HSV?

hsl(69, 93%, 60%) and hsv(69, 77%, 97%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #dbf839 a light or a dark color?

It is a light color. Relative luminance is 0.8249 and perceived brightness is 88%, so black text on it reaches 17.50:1.

Should I use black or white text on #dbf839?

Black. It scores 17.50:1 against #dbf839, versus 1.20:1 for white — AAA at any size.

Is #dbf839 accessible on a white background?

#dbf839 on white scores 1.20:1, which fails WCAG AA at every size. Darken it to #687A04 to reach 4.5:1, or #4F5D03 for 7:1.

What is the complementary color of #dbf839?

#5639F8 sits directly opposite on the wheel. Softer options are the split-complements #397CF8 and #B539F8, which give the same contrast with far less vibration.

What colors go well with #dbf839?

For interface work: #F9FAF4 as the surface, #E6EDC0 for borders, #8F9B4B for secondary text, #3548FC as an accent and #697B04 for hover and pressed states. For a palette, the analogous pair #F8B539 and #7CF839 stays calm, while #5639F8 is the loudest partner.

What is #dbf839 in CMYK for printing?

cmyk(12%, 0%, 77%, 3%). 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 #dbf839 warm or cool?

Warm — it scores 33 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F8CF39; nudged cooler, #95FA37.

Which Tailwind color is closest to #dbf839?

The lime family — its 500 step is #84cc16, ΔE2000 14.1 away. That is a visible difference, so define #dbf839 as a custom token rather than reaching for the built-in.

How do I use #dbf839 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#dbf839] or text-[#dbf839], 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 #dbf839 with 50% opacity?

rgba(219, 248, 57, 0.5), or #dbf83980 in eight-digit hex. Over white that composites to #EDFC9C; over black, #6E7C1D.

Is #dbf839 a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 3.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #dbf839 mean?

As a yellow, it reads optimistic, alert, cheap-and-cheerful. The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #dbf839?
