Color scale — 50 to 950

How to use #a77c01

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 #7F5E01
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.

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.

What each alpha value actually composites to. The top row is #a77c01 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.

#a77c01, answered

What color is #a77c01?

#a77c01 is a dark electric yellow, closest to Dark Goldenrod (ΔE2000 4.4). It sits at 45° on the hue wheel with 99% saturation and 33% lightness, which reads as warm.

What is the RGB value of #a77c01?

rgb(167, 124, 1) — 167 red, 124 green and 1 blue out of 255, or 65.5% / 48.6% / 0.4% by channel.

What is #a77c01 in HSL and HSV?

hsl(45, 99%, 33%) and hsv(44, 99%, 65%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a77c01 a light or a dark color?

It is a mid-tone. Relative luminance is 0.2263 and perceived brightness is 52%, so black text on it reaches 5.53:1.

Should I use black or white text on #a77c01?

Black. It scores 5.53:1 against #a77c01, versus 3.80:1 for white — AA at any size.

Is #a77c01 accessible on a white background?

#a77c01 on white scores 3.80:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #936D01 to reach 4.5:1, or #6F5301 for 7:1.

What is the complementary color of #a77c01?

#012CA7 sits directly opposite on the wheel. Softer options are the split-complements #017FA7 and #2901A7, which give the same contrast with far less vibration.

What colors go well with #a77c01?

For interface work: #FAF9F4 as the surface, #EDE1C0 for borders, #9B864B for secondary text, #0055A8 as an accent and #7F5E01 for hover and pressed states. For a palette, the analogous pair #A72901 and #7FA701 stays calm, while #012CA7 is the loudest partner.

What is #a77c01 in CMYK for printing?

cmyk(0%, 26%, 99%, 35%). 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 #a77c01 warm or cool?

Warm — it scores 12 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A75D01; nudged cooler, #96A800.

Which Tailwind color is closest to #a77c01?

The amber family — its 500 step is #f59e0b, ΔE2000 17.1 away. That is a visible difference, so define #a77c01 as a custom token rather than reaching for the built-in.

How do I use #a77c01 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a77c01] or text-[#a77c01], 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 #a77c01 with 50% opacity?
