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.

How to use #eca331

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
  • 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 #754B0B
Safe as a 1px border on white
No — use #CD8413

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

friendlyenergeticaffordablesocial

Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing.

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

Hard to make feel premium, and it collides with the "caution" band in status systems.

Transparency

What each alpha value actually composites to. The top row is #eca331 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.

#eca331, answered

What color is #eca331?

#eca331 is a balanced electric orange, closest to Orange (ΔE2000 4). It sits at 37° on the hue wheel with 83% saturation and 56% lightness, which reads as warm.

What is the RGB value of #eca331?

rgb(236, 163, 49) — 236 red, 163 green and 49 blue out of 255, or 92.5% / 63.9% / 19.2% by channel.

What is #eca331 in HSL and HSV?

hsl(37, 83%, 56%) and hsv(37, 79%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #eca331 a light or a dark color?

It is a mid-tone. Relative luminance is 0.4425 and perceived brightness is 71%, so black text on it reaches 9.85:1.

Should I use black or white text on #eca331?

Black. It scores 9.85:1 against #eca331, versus 2.13:1 for white — AAA at any size.

Is #eca331 accessible on a white background?

#eca331 on white scores 2.13:1, which fails WCAG AA at every size. Darken it to #A3690F to reach 4.5:1, or #794E0B for 7:1.

What is the complementary color of #eca331?

#317AEC sits directly opposite on the wheel. Softer options are the split-complements #31D7EC and #4631EC, which give the same contrast with far less vibration.

What colors go well with #eca331?

For interface work: #FAF8F4 as the surface, #EDDBC0 for borders, #9B7C4B for secondary text, #0E7FBE as an accent and #754B0B for hover and pressed states. For a palette, the analogous pair #EC4631 and #D7EC31 stays calm, while #317AEC is the loudest partner.

What is #eca331 in CMYK for printing?

cmyk(0%, 31%, 79%, 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 #eca331 warm or cool?

Warm — it scores 6 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EC9031; nudged cooler, #EEEA2F.

Which Tailwind color is closest to #eca331?

The amber family — its 500 step is #f59e0b, ΔE2000 3 away. That is a visible difference, so define #eca331 as a custom token rather than reaching for the built-in.

How do I use #eca331 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#eca331] or text-[#eca331], 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 #eca331 with 50% opacity?

rgba(236, 163, 49, 0.5), or #eca33180 in eight-digit hex. Over white that composites to #F6D198; over black, #765219.

Is #eca331 a web-safe color?

No. The nearest web-safe colour is #FF9933, ΔE2000 7.7 away. The palette only matters for legacy displays and some email clients now.

What does the color #eca331 mean?

As a orange, it reads friendly, energetic, affordable. Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #eca331?

The safest is same-hue elevation: linear-gradient(135deg, #F1BC69, #eca331 45%, #754B0B). For more colour, a short hue run to #9DE916 keeps it rich without turning muddy.
