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 #af9b05

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 #7C6E04
Safe as a 1px border on white
No — use #A59205

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 #af9b05 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.

#af9b05, answered

What color is #af9b05?

#af9b05 is a dark electric yellow, closest to Goldenrod (ΔE2000 10.4). It sits at 53° on the hue wheel with 94% saturation and 35% lightness, which reads as warm.

What is the RGB value of #af9b05?

rgb(175, 155, 5) — 175 red, 155 green and 5 blue out of 255, or 68.6% / 60.8% / 2% by channel.

What is #af9b05 in HSL and HSV?

hsl(53, 94%, 35%) and hsv(53, 97%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #af9b05 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3257 and perceived brightness is 60%, so black text on it reaches 7.51:1.

Should I use black or white text on #af9b05?

Black. It scores 7.51:1 against #af9b05, versus 2.79:1 for white — AAA at any size.

Is #af9b05 accessible on a white background?

#af9b05 on white scores 2.79:1, which fails WCAG AA at every size. Darken it to #827304 to reach 4.5:1, or #655903 for 7:1.

What is the complementary color of #af9b05?

#0519AF sits directly opposite on the wheel. Softer options are the split-complements #056EAF and #4605AF, which give the same contrast with far less vibration.

What colors go well with #af9b05?

For interface work: #FAFAF4 as the surface, #EDE7C0 for borders, #9B914B for secondary text, #0143B3 as an accent and #7C6E04 for hover and pressed states. For a palette, the analogous pair #AF4605 and #6EAF05 stays calm, while #0519AF is the loudest partner.

What is #af9b05 in CMYK for printing?

cmyk(0%, 11%, 97%, 31%). 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 #af9b05 warm or cool?

Warm — it scores 19 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AF6E05; nudged cooler, #86B103.

Which Tailwind color is closest to #af9b05?

The yellow family — its 500 step is #eab308, ΔE2000 12.6 away. That is a visible difference, so define #af9b05 as a custom token rather than reaching for the built-in.

How do I use #af9b05 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#af9b05] or text-[#af9b05], 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 #af9b05 with 50% opacity?

rgba(175, 155, 5, 0.5), or #af9b0580 in eight-digit hex. Over white that composites to #D7CD82; over black, #584E03.

Is #af9b05 a web-safe color?

No. The nearest web-safe colour is #999900, ΔE2000 5.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #af9b05 mean?
