How to use #f57729

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 #7A3206
Safe as a 1px border on white
No — use #F46B16

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.

#f57729, answered

What color is #f57729?

#f57729 is a balanced electric orange, closest to Coral (ΔE2000 6.9). It sits at 23° on the hue wheel with 91% saturation and 56% lightness, which reads as warm.

What is the RGB value of #f57729?

rgb(245, 119, 41) — 245 red, 119 green and 41 blue out of 255, or 96.1% / 46.7% / 16.1% by channel.

What is #f57729 in HSL and HSV?

hsl(23, 91%, 56%) and hsv(23, 83%, 96%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #f57729 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3277 and perceived brightness is 64%, so black text on it reaches 7.55:1.

Should I use black or white text on #f57729?

Black. It scores 7.55:1 against #f57729, versus 2.78:1 for white — AAA at any size.

Is #f57729 accessible on a white background?

#f57729 on white scores 2.78:1, which fails WCAG AA at every size. Darken it to #C85209 to reach 4.5:1, or #933C07 for 7:1.

What is the complementary color of #f57729?

#29A7F5 sits directly opposite on the wheel. Softer options are the split-complements #29F5DD and #2941F5, which give the same contrast with far less vibration.

What colors go well with #f57729?

For interface work: #FAF7F4 as the surface, #EDD1C0 for borders, #9B694B for secondary text, #05ADC7 as an accent and #7A3206 for hover and pressed states. For a palette, the analogous pair #F52941 and #F5DD29 stays calm, while #29A7F5 is the loudest partner.

What is #f57729 in CMYK for printing?

cmyk(0%, 51%, 83%, 4%). 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 #f57729 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 #F68B41; nudged cooler, #F72A27.

Which Tailwind color is closest to #f57729?

The orange family — its 500 step is #f97316, ΔE2000 1.6 away. That is close enough to swap in without anyone noticing.

How do I use #f57729 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#f57729] or text-[#f57729], 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 #f57729 with 50% opacity?

rgba(245, 119, 41, 0.5), or #f5772980 in eight-digit hex. Over white that composites to #FABB94; over black, #7B3C15.

Is #f57729 a web-safe color?
