Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #a39430 is pinned to step 700; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.

How to use #a39430

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Headings from 24px up on white
  • 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
  • Small text on white — under 4.5:1
  • 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
24px / 18.66px bold
Safe as a fill behind white type
No — use #62591D
Safe as a 1px border on white
Yes

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 #a39430 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.

#a39430, answered

What color is #a39430?

#a39430 is a dark vivid yellow, closest to Olive (ΔE2000 9.3). It sits at 52° on the hue wheel with 55% saturation and 41% lightness, which reads as warm.

What is the RGB value of #a39430?

rgb(163, 148, 48) — 163 red, 148 green and 48 blue out of 255, or 63.9% / 58% / 18.8% by channel.

What is #a39430 in HSL and HSV?

hsl(52, 55%, 41%) and hsv(52, 71%, 64%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a39430 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2918 and perceived brightness is 57%, so black text on it reaches 6.84:1.

Should I use black or white text on #a39430?

Black. It scores 6.84:1 against #a39430, versus 3.07:1 for white — AA at any size.

Is #a39430 accessible on a white background?

#a39430 on white scores 3.07:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #807426 to reach 4.5:1, or #60571C for 7:1.

What is the complementary color of #a39430?

#303FA3 sits directly opposite on the wheel. Softer options are the split-complements #3079A3 and #5B30A3, which give the same contrast with far less vibration.

What colors go well with #a39430?

For interface work: #FAFAF4 as the surface, #ECE7C0 for borders, #9B904B for secondary text, #2C5BA7 as an accent and #62591D for hover and pressed states. For a palette, the analogous pair #A35B30 and #79A330 stays calm, while #303FA3 is the loudest partner.

What is #a39430 in CMYK for printing?

cmyk(0%, 9%, 71%, 36%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a39430 warm or cool?

Warm — it scores 18 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A37230; nudged cooler, #89A52E.

Which Tailwind color is closest to #a39430?

The yellow family — its 500 step is #eab308, ΔE2000 15.9 away. That is a visible difference, so define #a39430 as a custom token rather than reaching for the built-in.

How do I use #a39430 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a39430] or text-[#a39430], 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 #a39430 with 50% opacity?
