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 #cf9b18

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
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #72560D
Safe as a 1px border on white
No — use #BD8D16

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 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.

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.

#cf9b18, answered

What color is #cf9b18?

#cf9b18 is a balanced electric yellow, closest to Goldenrod (ΔE2000 2.9). It sits at 43° on the hue wheel with 79% saturation and 45% lightness, which reads as warm.

What is the RGB value of #cf9b18?

rgb(207, 155, 24) — 207 red, 155 green and 24 blue out of 255, or 81.2% / 60.8% / 9.4% by channel.

What is #cf9b18 in HSL and HSV?

hsl(43, 79%, 45%) and hsv(43, 88%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #cf9b18 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3677 and perceived brightness is 64%, so black text on it reaches 8.35:1.

Should I use black or white text on #cf9b18?

Black. It scores 8.35:1 against #cf9b18, versus 2.51:1 for white — AAA at any size.

Is #cf9b18 accessible on a white background?

#cf9b18 on white scores 2.51:1, which fails WCAG AA at every size. Darken it to #946F11 to reach 4.5:1, or #6F530D for 7:1.

What is the complementary color of #cf9b18?

#184CCF sits directly opposite on the wheel. Softer options are the split-complements #18A7CF and #4018CF, which give the same contrast with far less vibration.

What colors go well with #cf9b18?

For interface work: #FAF9F4 as the surface, #EDE0C0 for borders, #9B844B for secondary text, #137AD4 as an accent and #72560D for hover and pressed states. For a palette, the analogous pair #CF4018 and #A7CF18 stays calm, while #184CCF is the loudest partner.

What is #cf9b18 in CMYK for printing?

cmyk(0%, 25%, 88%, 19%). 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 #cf9b18 warm or cool?

Warm — it scores 11 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CF7D18; nudged cooler, #C2D116.

Which Tailwind color is closest to #cf9b18?

The yellow family — its 500 step is #eab308, ΔE2000 7.2 away. That is a visible difference, so define #cf9b18 as a custom token rather than reaching for the built-in.

How do I use #cf9b18 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#cf9b18] or text-[#cf9b18], 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 #cf9b18 with 50% opacity?

rgba(207, 155, 24, 0.5), or #cf9b1880 in eight-digit hex. Over white that composites to #E7CD8C; over black, #684E0C.

Is #cf9b18 a web-safe color?

No. The nearest web-safe colour is #CC9900, ΔE2000 1.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #cf9b18 mean?
