Colour vision deficiency

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 #afb351

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • 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 #575927
Safe as a 1px border on white
No — use #959943

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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

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 #afb351 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.

#afb351, answered

What color is #afb351?

#afb351 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 4.6). It sits at 62° on the hue wheel with 39% saturation and 51% lightness, which reads as warm.

What is the RGB value of #afb351?

rgb(175, 179, 81) — 175 red, 179 green and 81 blue out of 255, or 68.6% / 70.2% / 31.8% by channel.

What is #afb351 in HSL and HSV?

hsl(62, 39%, 51%) and hsv(62, 55%, 70%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #afb351 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4195 and perceived brightness is 66%, so black text on it reaches 9.39:1.

Should I use black or white text on #afb351?

Black. It scores 9.39:1 against #afb351, versus 2.24:1 for white — AAA at any size.

Is #afb351 accessible on a white background?

#afb351 on white scores 2.24:1, which fails WCAG AA at every size. Darken it to #767935 to reach 4.5:1, or #5A5C28 for 7:1.

What is the complementary color of #afb351?

#5551B3 sits directly opposite on the wheel. Softer options are the split-complements #517EB3 and #8651B3, which give the same contrast with far less vibration.

What colors go well with #afb351?

For interface work: #FAFAF4 as the surface, #E5E6C6 for borders, #989B4B for secondary text, #4C63B8 as an accent and #575927 for hover and pressed states. For a palette, the analogous pair #B38651 and #7EB351 stays calm, while #5551B3 is the loudest partner.

What is #afb351 in CMYK for printing?

cmyk(2%, 0%, 55%, 30%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #afb351 warm or cool?

Warm — it scores 27 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B39351; nudged cooler, #8CB64F.

Which Tailwind color is closest to #afb351?

The lime family — its 500 step is #84cc16, ΔE2000 12.9 away. That is a visible difference, so define #afb351 as a custom token rather than reaching for the built-in.

How do I use #afb351 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#afb351] or text-[#afb351], 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 #afb351 with 50% opacity?

rgba(175, 179, 81, 0.5), or #afb35180 in eight-digit hex. Over white that composites to #D7D9A8; over black, #585A29.

Is #afb351 a web-safe color?

No. The nearest web-safe colour is #99CC66, ΔE2000 11 away. The palette only matters for legacy displays and some email clients now.

What does the color #afb351 mean?
