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 #fdcd01

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 #7F6701
Safe as a 1px border on white
No — use #B18F01

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.

#fdcd01, answered

What color is #fdcd01?

#fdcd01 is a balanced electric yellow, closest to Gold (ΔE2000 3). It sits at 49° on the hue wheel with 99% saturation and 50% lightness, which reads as warm.

What is the RGB value of #fdcd01?

rgb(253, 205, 1) — 253 red, 205 green and 1 blue out of 255, or 99.2% / 80.4% / 0.4% by channel.

What is #fdcd01 in HSL and HSV?

hsl(49, 99%, 50%) and hsv(49, 100%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #fdcd01 a light or a dark color?

It is a light color. Relative luminance is 0.6455 and perceived brightness is 82%, so black text on it reaches 13.91:1.

Should I use black or white text on #fdcd01?

Black. It scores 13.91:1 against #fdcd01, versus 1.51:1 for white — AAA at any size.

Is #fdcd01 accessible on a white background?

#fdcd01 on white scores 1.51:1, which fails WCAG AA at every size. Darken it to #8D7201 to reach 4.5:1, or #6A5600 for 7:1.

What is the complementary color of #fdcd01?

#0131FD sits directly opposite on the wheel. Softer options are the split-complements #01AFFD and #4F01FD, which give the same contrast with far less vibration.

What colors go well with #fdcd01?

For interface work: #FAF9F4 as the surface, #EDE4C0 for borders, #9B8C4B for secondary text, #0070FE as an accent and #7F6701 for hover and pressed states. For a palette, the analogous pair #FD4F01 and #AFFD01 stays calm, while #0131FD is the loudest partner.

What is #fdcd01 in CMYK for printing?

cmyk(0%, 19%, 100%, 1%). 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 #fdcd01 warm or cool?

Warm — it scores 16 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FD9E01; nudged cooler, #D1FE00.

Which Tailwind color is closest to #fdcd01?

The yellow family — its 500 step is #eab308, ΔE2000 6.8 away. That is a visible difference, so define #fdcd01 as a custom token rather than reaching for the built-in.

How do I use #fdcd01 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#fdcd01] or text-[#fdcd01], 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 #fdcd01 with 50% opacity?

rgba(253, 205, 1, 0.5), or #fdcd0180 in eight-digit hex. Over white that composites to #FEE680; over black, #7F6701.

Is #fdcd01 a web-safe color?

No. The nearest web-safe colour is #FFCC00, ΔE2000 0.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #fdcd01 mean?

As a yellow, it reads optimistic, alert, cheap-and-cheerful. The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #fdcd01?

The safest is same-hue elevation: linear-gradient(135deg, #FEDA3D, #fdcd01 45%, #7F6701). For more colour, a short hue run to #62DE01 keeps it rich without turning muddy.
