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 #ecdd13

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 #766F09
Safe as a 1px border on white
No — use #A0960D

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.

Transparency

What each alpha value actually composites to. The top row is #ecdd13 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.

#ecdd13, answered

What color is #ecdd13?

#ecdd13 is a balanced electric yellow, closest to Gold (ΔE2000 6). It sits at 56° on the hue wheel with 85% saturation and 50% lightness, which reads as warm.

What is the RGB value of #ecdd13?

rgb(236, 221, 19) — 236 red, 221 green and 19 blue out of 255, or 92.5% / 86.7% / 7.5% by channel.

What is #ecdd13 in HSL and HSV?

hsl(56, 85%, 50%) and hsv(56, 92%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ecdd13 a light or a dark color?

It is a light color. Relative luminance is 0.6959 and perceived brightness is 84%, so black text on it reaches 14.92:1.

Should I use black or white text on #ecdd13?

Black. It scores 14.92:1 against #ecdd13, versus 1.41:1 for white — AAA at any size.

Is #ecdd13 accessible on a white background?

#ecdd13 on white scores 1.41:1, which fails WCAG AA at every size. Darken it to #7F770A to reach 4.5:1, or #5E5808 for 7:1.

What is the complementary color of #ecdd13?

#1322EC sits directly opposite on the wheel. Softer options are the split-complements #138EEC and #7113EC, which give the same contrast with far less vibration.

What colors go well with #ecdd13?

For interface work: #FAFAF4 as the surface, #EDEAC0 for borders, #9B954B for secondary text, #0E56F1 as an accent and #766F09 for hover and pressed states. For a palette, the analogous pair #EC7113 and #8EEC13 stays calm, while #1322EC is the loudest partner.

What is #ecdd13 in CMYK for printing?

cmyk(0%, 6%, 92%, 8%). 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 #ecdd13 warm or cool?

Warm — it scores 22 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #ECA413; nudged cooler, #ACEF10.

Which Tailwind color is closest to #ecdd13?

The yellow family — its 500 step is #eab308, ΔE2000 13.8 away. That is a visible difference, so define #ecdd13 as a custom token rather than reaching for the built-in.

How do I use #ecdd13 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ecdd13] or text-[#ecdd13], 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 #ecdd13 with 50% opacity?

rgba(236, 221, 19, 0.5), or #ecdd1380 in eight-digit hex. Over white that composites to #F6EE89; over black, #766F0A.

Is #ecdd13 a web-safe color?

No. The nearest web-safe colour is #FFCC00, ΔE2000 9.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #ecdd13 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 #ecdd13?

The safest is same-hue elevation: linear-gradient(135deg, #F1E54C, #ecdd13 45%, #766F09). For more colour, a short hue run to #4ED011 keeps it rich without turning muddy.
