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 #dfb901

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
  • 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 #7F6901
Safe as a 1px border on white
No — use #AC8F01

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 low lightness adds weight and formality.

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 #dfb901 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.

#dfb901, answered

What color is #dfb901?

#dfb901 is a dark electric yellow, closest to Goldenrod (ΔE2000 7.2). It sits at 50° on the hue wheel with 99% saturation and 44% lightness, which reads as warm.

What is the RGB value of #dfb901?

rgb(223, 185, 1) — 223 red, 185 green and 1 blue out of 255, or 87.5% / 72.5% / 0.4% by channel.

What is #dfb901 in HSL and HSV?

hsl(50, 99%, 44%) and hsv(50, 100%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #dfb901 a light or a dark color?

It is a light color. Relative luminance is 0.5039 and perceived brightness is 73%, so black text on it reaches 11.08:1.

Should I use black or white text on #dfb901?

Black. It scores 11.08:1 against #dfb901, versus 1.90:1 for white — AAA at any size.

Is #dfb901 accessible on a white background?

#dfb901 on white scores 1.90:1, which fails WCAG AA at every size. Darken it to #897101 to reach 4.5:1, or #655400 for 7:1.

What is the complementary color of #dfb901?

#0127DF sits directly opposite on the wheel. Softer options are the split-complements #0196DF and #4A01DF, which give the same contrast with far less vibration.

What colors go well with #dfb901?

For interface work: #FAF9F4 as the surface, #EDE5C0 for borders, #9B8D4B for secondary text, #005EE0 as an accent and #7F6901 for hover and pressed states. For a palette, the analogous pair #DF4A01 and #96DF01 stays calm, while #0127DF is the loudest partner.

What is #dfb901 in CMYK for printing?

cmyk(0%, 17%, 100%, 13%). 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 #dfb901 warm or cool?

Warm — it scores 16 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF8B01; nudged cooler, #B4E000.

Which Tailwind color is closest to #dfb901?

The yellow family — its 500 step is #eab308, ΔE2000 4.7 away. That is a visible difference, so define #dfb901 as a custom token rather than reaching for the built-in.

How do I use #dfb901 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#dfb901] or text-[#dfb901], 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 #dfb901 with 50% opacity?

rgba(223, 185, 1, 0.5), or #dfb90180 in eight-digit hex. Over white that composites to #EFDC80; over black, #705D01.

Is #dfb901 a web-safe color?

No. The nearest web-safe colour is #CCCC00, ΔE2000 10 away. The palette only matters for legacy displays and some email clients now.

What does the color #dfb901 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.
