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 #ea9521

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 #74480B
Safe as a 1px border on white
No — use #D48214

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.

What each alpha value actually composites to. The top row is #ea9521 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.

#ea9521, answered

What color is #ea9521?

#ea9521 is a balanced electric orange, closest to Orange (ΔE2000 5.6). It sits at 35° on the hue wheel with 83% saturation and 52% lightness, which reads as warm.

What is the RGB value of #ea9521?

rgb(234, 149, 33) — 234 red, 149 green and 33 blue out of 255, or 91.8% / 58.4% / 12.9% by channel.

What is #ea9521 in HSL and HSV?

hsl(35, 83%, 52%) and hsv(35, 86%, 92%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ea9521 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3910 and perceived brightness is 67%, so black text on it reaches 8.82:1.

Should I use black or white text on #ea9521?

Black. It scores 8.82:1 against #ea9521, versus 2.38:1 for white — AAA at any size.

Is #ea9521 accessible on a white background?

#ea9521 on white scores 2.38:1, which fails WCAG AA at every size. Darken it to #A56610 to reach 4.5:1, or #7B4C0C for 7:1.

What is the complementary color of #ea9521?

#2176EA sits directly opposite on the wheel. Softer options are the split-complements #21DBEA and #3121EA, which give the same contrast with far less vibration.

What colors go well with #ea9521?

For interface work: #FAF8F4 as the surface, #EDDAC0 for borders, #9B794B for secondary text, #0D85BF as an accent and #74480B for hover and pressed states. For a palette, the analogous pair #EA3121 and #DBEA21 stays calm, while #2176EA is the loudest partner.

What is #ea9521 in CMYK for printing?

cmyk(0%, 36%, 86%, 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 #ea9521 warm or cool?

Warm — it scores 4 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EC9139; nudged cooler, #ECE11F.

Which Tailwind color is closest to #ea9521?

The amber family — its 500 step is #f59e0b, ΔE2000 3.5 away. That is a visible difference, so define #ea9521 as a custom token rather than reaching for the built-in.

How do I use #ea9521 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ea9521] or text-[#ea9521], 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 #ea9521 with 50% opacity?

rgba(234, 149, 33, 0.5), or #ea952180 in eight-digit hex. Over white that composites to #F5CA90; over black, #754B11.

Is #ea9521 a web-safe color?

No. The nearest web-safe colour is #FF9933, ΔE2000 5.2 away. The palette only matters for legacy displays and some email clients now.

What does the color #ea9521 mean?
