How to use #b5a607

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 #7B7105
Safe as a 1px border on white
No — use #A29406

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 #b5a607 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.

#b5a607, answered

What color is #b5a607?

#b5a607 is a dark electric yellow, closest to Dark Khaki (ΔE2000 10.1). It sits at 55° on the hue wheel with 93% saturation and 37% lightness, which reads as warm.

What is the RGB value of #b5a607?

rgb(181, 166, 7) — 181 red, 166 green and 7 blue out of 255, or 71% / 65.1% / 2.7% by channel.

What is #b5a607 in HSL and HSV?

hsl(55, 93%, 37%) and hsv(55, 96%, 71%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b5a607 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3711 and perceived brightness is 63%, so black text on it reaches 8.42:1.

Should I use black or white text on #b5a607?

Black. It scores 8.42:1 against #b5a607, versus 2.49:1 for white — AAA at any size.

Is #b5a607 accessible on a white background?

#b5a607 on white scores 2.49:1, which fails WCAG AA at every size. Darken it to #7F7505 to reach 4.5:1, or #625A04 for 7:1.

What is the complementary color of #b5a607?

#0716B5 sits directly opposite on the wheel. Softer options are the split-complements #076DB5 and #4F07B5, which give the same contrast with far less vibration.

What colors go well with #b5a607?

For interface work: #FAFAF4 as the surface, #EDE9C0 for borders, #9B944B for secondary text, #0340B9 as an accent and #7B7105 for hover and pressed states. For a palette, the analogous pair #B54F07 and #6DB507 stays calm, while #0716B5 is the loudest partner.

What is #b5a607 in CMYK for printing?

cmyk(0%, 8%, 96%, 29%). 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 #b5a607 warm or cool?

Warm — it scores 21 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B57607; nudged cooler, #85B705.

Which Tailwind color is closest to #b5a607?

The yellow family — its 500 step is #eab308, ΔE2000 11.9 away. That is a visible difference, so define #b5a607 as a custom token rather than reaching for the built-in.

How do I use #b5a607 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b5a607] or text-[#b5a607], 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 #b5a607 with 50% opacity?
