How to use #da613f

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Headings from 24px up on white
  • 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
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
24px / 18.66px bold
Safe as a fill behind white type
No — use #6B2815
Safe as a 1px border on white
Yes

Meaning and mood

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

urgentappetisingboldphysical

Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

Worth knowing

It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

What each alpha value actually composites to. The top row is #da613f 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.

#da613f, answered

What color is #da613f?

#da613f is a balanced vivid red, closest to Tomato (ΔE2000 7). It sits at 13° on the hue wheel with 68% saturation and 55% lightness, which reads as warm.

What is the RGB value of #da613f?

rgb(218, 97, 63) — 218 red, 97 green and 63 blue out of 255, or 85.5% / 38% / 24.7% by channel.

What is #da613f in HSL and HSV?

hsl(13, 68%, 55%) and hsv(13, 71%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #da613f a light or a dark color?

It is a mid-tone. Relative luminance is 0.2381 and perceived brightness is 56%, so black text on it reaches 5.76:1.

Should I use black or white text on #da613f?

Black. It scores 5.76:1 against #da613f, versus 3.64:1 for white — AA at any size.

Is #da613f accessible on a white background?

#da613f on white scores 3.64:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #C94B27 to reach 4.5:1, or #9A391E for 7:1.

What is the complementary color of #da613f?

#3FB8DA sits directly opposite on the wheel. Softer options are the split-complements #3FDAAF and #3F6ADA, which give the same contrast with far less vibration.

What colors go well with #da613f?

For interface work: #FAF6F4 as the surface, #EDCAC0 for borders, #9B5C4B for secondary text, #1CB0AB as an accent and #6B2815 for hover and pressed states. For a palette, the analogous pair #DA3F6A and #DAAF3F stays calm, while #3FB8DA is the loudest partner.

What is #da613f in CMYK for printing?

cmyk(0%, 56%, 71%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #da613f warm or cool?

Warm — it scores 9 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DA743F; nudged cooler, #DC3D54.

Which Tailwind color is closest to #da613f?

The red family — its 500 step is #ef4444, ΔE2000 8.6 away. That is a visible difference, so define #da613f as a custom token rather than reaching for the built-in.

How do I use #da613f in Tailwind CSS?

Inline it as an arbitrary value with bg-[#da613f] or text-[#da613f], 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 #da613f with 50% opacity?

rgba(218, 97, 63, 0.5), or #da613f80 in eight-digit hex. Over white that composites to #EDB09F; over black, #6D3120.

Is #da613f a web-safe color?

No. The nearest web-safe colour is #CC6633, ΔE2000 5.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #da613f mean?
