How to use #b8b607

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 #7B7905
Safe as a 1px border on white
No — use #9B9906

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 #b8b607 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.

#b8b607, answered

What color is #b8b607?

#b8b607 is a dark electric yellow, closest to Dark Khaki (ΔE2000 9.6). It sits at 59° on the hue wheel with 93% saturation and 38% lightness, which reads as warm.

What is the RGB value of #b8b607?

rgb(184, 182, 7) — 184 red, 182 green and 7 blue out of 255, or 72.2% / 71.4% / 2.7% by channel.

What is #b8b607 in HSL and HSV?

hsl(59, 93%, 38%) and hsv(59, 96%, 72%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #b8b607 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4366 and perceived brightness is 67%, so black text on it reaches 9.73:1.

Should I use black or white text on #b8b607?

Black. It scores 9.73:1 against #b8b607, versus 2.16:1 for white — AAA at any size.

Is #b8b607 accessible on a white background?

#b8b607 on white scores 2.16:1, which fails WCAG AA at every size. Darken it to #787705 to reach 4.5:1, or #5B5A03 for 7:1.

What is the complementary color of #b8b607?

#0709B8 sits directly opposite on the wheel. Softer options are the split-complements #0762B8 and #5E07B8, which give the same contrast with far less vibration.

What colors go well with #b8b607?

For interface work: #FAFAF4 as the surface, #EDECC0 for borders, #9B9A4B for secondary text, #0334BC as an accent and #7B7905 for hover and pressed states. For a palette, the analogous pair #B85E07 and #62B807 stays calm, while #0709B8 is the loudest partner.

What is #b8b607 in CMYK for printing?

cmyk(0%, 1%, 96%, 28%). 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 #b8b607 warm or cool?

Warm — it scores 24 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B87D07; nudged cooler, #7ABA05.

Which Tailwind color is closest to #b8b607?

The yellow family — its 500 step is #eab308, ΔE2000 14 away. That is a visible difference, so define #b8b607 as a custom token rather than reaching for the built-in.

How do I use #b8b607 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#b8b607] or text-[#b8b607], 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 #b8b607 with 50% opacity?

rgba(184, 182, 7, 0.5), or #b8b60780 in eight-digit hex. Over white that composites to #DCDB83; over black, #5C5B04.
