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 #b2a721

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 #6C6514
Safe as a 1px border on white
No — use #A1971E

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.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. 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 #b2a721 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.

#b2a721, answered

What color is #b2a721?

#b2a721 is a dark vivid yellow, closest to Dark Khaki (ΔE2000 8.9). It sits at 55° on the hue wheel with 69% saturation and 41% lightness, which reads as warm.

What is the RGB value of #b2a721?

rgb(178, 167, 33) — 178 red, 167 green and 33 blue out of 255, or 69.8% / 65.5% / 12.9% by channel.

What is #b2a721 in HSL and HSV?

hsl(55, 69%, 41%) and hsv(55, 81%, 70%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b2a721 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3721 and perceived brightness is 63%, so black text on it reaches 8.44:1.

Should I use black or white text on #b2a721?

Black. It scores 8.44:1 against #b2a721, versus 2.49:1 for white — AAA at any size.

Is #b2a721 accessible on a white background?

#b2a721 on white scores 2.49:1, which fails WCAG AA at every size. Darken it to #7E7717 to reach 4.5:1, or #605A12 for 7:1.

What is the complementary color of #b2a721?

#212CB2 sits directly opposite on the wheel. Softer options are the split-complements #2175B2 and #5E21B2, which give the same contrast with far less vibration.

What colors go well with #b2a721?

For interface work: #FAFAF4 as the surface, #EDE9C0 for borders, #9B954B for secondary text, #1D4FB6 as an accent and #6C6514 for hover and pressed states. For a palette, the analogous pair #B25E21 and #75B221 stays calm, while #212CB2 is the loudest partner.

What is #b2a721 in CMYK for printing?

cmyk(0%, 6%, 82%, 30%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #b2a721 warm or cool?

Warm — it scores 21 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B27A21; nudged cooler, #89B41F.

Which Tailwind color is closest to #b2a721?

The yellow family — its 500 step is #eab308, ΔE2000 13 away. That is a visible difference, so define #b2a721 as a custom token rather than reaching for the built-in.

How do I use #b2a721 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b2a721] or text-[#b2a721], 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 #b2a721 with 50% opacity?

rgba(178, 167, 33, 0.5), or #b2a72180 in eight-digit hex. Over white that composites to #D9D390; over black, #595411.
