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 #aea921

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 #6B6814
Safe as a 1px border on white
No — use #9D981E

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 #aea921 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.

#aea921, answered

What color is #aea921?

#aea921 is a dark vivid yellow, closest to Dark Khaki (ΔE2000 8.7). It sits at 58° on the hue wheel with 68% saturation and 41% lightness, which reads as warm.

What is the RGB value of #aea921?

rgb(174, 169, 33) — 174 red, 169 green and 33 blue out of 255, or 68.2% / 66.3% / 12.9% by channel.

What is #aea921 in HSL and HSV?

hsl(58, 68%, 41%) and hsv(58, 81%, 68%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #aea921 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3748 and perceived brightness is 63%, so black text on it reaches 8.50:1.

Should I use black or white text on #aea921?

Black. It scores 8.50:1 against #aea921, versus 2.47:1 for white — AAA at any size.

Is #aea921 accessible on a white background?

#aea921 on white scores 2.47:1, which fails WCAG AA at every size. Darken it to #7B7717 to reach 4.5:1, or #5D5A12 for 7:1.

What is the complementary color of #aea921?

#2126AE sits directly opposite on the wheel. Softer options are the split-complements #216CAE and #6321AE, which give the same contrast with far less vibration.

What colors go well with #aea921?

For interface work: #FAFAF4 as the surface, #EDEBC0 for borders, #9B984B for secondary text, #1D47B2 as an accent and #6B6814 for hover and pressed states. For a palette, the analogous pair #AE6321 and #6CAE21 stays calm, while #2126AE is the loudest partner.

What is #aea921 in CMYK for printing?

cmyk(0%, 3%, 81%, 32%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #aea921 warm or cool?

Warm — it scores 23 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AE7A21; nudged cooler, #80B01F.

Which Tailwind color is closest to #aea921?

The yellow family — its 500 step is #eab308, ΔE2000 14.4 away. That is a visible difference, so define #aea921 as a custom token rather than reaching for the built-in.

How do I use #aea921 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#aea921] or text-[#aea921], 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 #aea921 with 50% opacity?

rgba(174, 169, 33, 0.5), or #aea92180 in eight-digit hex. Over white that composites to #D7D490; over black, #575511.

Is #aea921 a web-safe color?

No. The nearest web-safe colour is #999933, ΔE2000 6.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #aea921 mean?
