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 #cb930f

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 #775609
Safe as a 1px border on white
No — use #BC880E

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.

#cb930f, answered

What color is #cb930f?

#cb930f is a dark electric yellow, closest to Dark Goldenrod (ΔE2000 4.8). It sits at 42° on the hue wheel with 86% saturation and 43% lightness, which reads as warm.

What is the RGB value of #cb930f?

rgb(203, 147, 15) — 203 red, 147 green and 15 blue out of 255, or 79.6% / 57.6% / 5.9% by channel.

What is #cb930f in HSL and HSV?

hsl(42, 86%, 43%) and hsv(42, 93%, 80%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cb930f a light or a dark color?

It is a mid-tone. Relative luminance is 0.3360 and perceived brightness is 62%, so black text on it reaches 7.72:1.

Should I use black or white text on #cb930f?

Black. It scores 7.72:1 against #cb930f, versus 2.72:1 for white — AAA at any size.

Is #cb930f accessible on a white background?

#cb930f on white scores 2.72:1, which fails WCAG AA at every size. Darken it to #976D0B to reach 4.5:1, or #715108 for 7:1.

What is the complementary color of #cb930f?

#0F47CB sits directly opposite on the wheel. Softer options are the split-complements #0FA5CB and #350FCB, which give the same contrast with far less vibration.

What colors go well with #cb930f?

For interface work: #FAF9F4 as the surface, #EDDFC0 for borders, #9B834B for secondary text, #0B76CF as an accent and #775609 for hover and pressed states. For a palette, the analogous pair #CB350F and #A5CB0F stays calm, while #0F47CB is the loudest partner.

What is #cb930f in CMYK for printing?

cmyk(0%, 28%, 93%, 20%). 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 #cb930f warm or cool?

Warm — it scores 10 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CB760F; nudged cooler, #C0CD0D.

Which Tailwind color is closest to #cb930f?

The amber family — its 500 step is #f59e0b, ΔE2000 8.8 away. That is a visible difference, so define #cb930f as a custom token rather than reaching for the built-in.

How do I use #cb930f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cb930f] or text-[#cb930f], 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 #cb930f with 50% opacity?

rgba(203, 147, 15, 0.5), or #cb930f80 in eight-digit hex. Over white that composites to #E5C987; over black, #664A08.

Is #cb930f a web-safe color?

No. The nearest web-safe colour is #CC9900, ΔE2000 2.6 away. The palette only matters for legacy displays and some email clients now.

What does the color #cb930f mean?
