}Best text color
Only one of black and white can be right. This is the one, with the number that proves it.
Make it accessible
A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.
Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #AF223F is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).
Accessibility — WCAG contrast
Contrast is symmetric, so each row covers both directions: #af223f as text on that neutral, and that neutral as text on #af223f.

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
A Tailwind-shaped ramp built around this exact hex. #af223f is pinned to step 700; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
The same eleven steps expressed in OKLCH, where equal lightness numbers actually look equally spaced. HSL ramps go muddy in the yellows and washed out in the blues; this one does not. Modern browsers render it natively — the hex ramp above is the fallback.

Not a palette — a role sheet. Each swatch answers one question you will hit while building the component.
Surface, border, heading and body all derive from this one hue, so the screen stays coherent without a second palette.
Lightness flips, hue holds. The accent stays the anchor in both themes.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
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 low lightness adds weight and formality.
It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

#af223f, answered
What color is #af223f?
#af223f is a dark vivid red, closest to Brown (ΔE2000 7.3). It sits at 348° on the hue wheel with 68% saturation and 41% lightness, which reads as warm.
What is the RGB value of #af223f?
rgb(175, 34, 63) — 175 red, 34 green and 63 blue out of 255, or 68.6% / 13.3% / 24.7% by channel.
What is #af223f in HSL and HSV?
hsl(348, 68%, 41%) and hsv(348, 81%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

It is a dark color. Relative luminance is 0.1062 and perceived brightness is 40%, so white text on it reaches 6.72:1.
Should I use black or white text on #af223f?
White. It scores 6.72:1 against #af223f, versus 3.12:1 for black — AA at any size.
Is #af223f accessible on a white background?
#af223f on white scores 6.72:1, which clears AA at every size but not AAA.
What is the complementary color of #af223f?
#22AF92 sits directly opposite on the wheel. Softer options are the split-complements #22AF4C and #2285AF, which give the same contrast with far less vibration.
What colors go well with #af223f?
For interface work: #FAF4F6 as the surface, #EDC0C9 for borders, #9B4B5B for secondary text, #1DAF6C as an accent and #6B1526 for hover and pressed states. For a palette, the analogous pair #AF2285 and #AF4C22 stays calm, while #22AF92 is the loudest partner.
What is #af223f in CMYK for printing?
cmyk(0%, 81%, 64%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.
Is #af223f warm or cool?
Warm — it scores 23 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AF3922; nudged cooler, #B12073.
Which Tailwind color is closest to #af223f?
The rose family — its 500 step is #f43f5e, ΔE2000 16.8 away. That is a visible difference, so define #af223f as a custom token rather than reaching for the built-in.
How do I use #af223f in Tailwind CSS?
Inline it as an arbitrary value with bg-[#af223f] or text-[#af223f], 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 #af223f with 50% opacity?
rgba(175, 34, 63, 0.5), or #af223f80 in eight-digit hex. Over white that composites to #D7919F; over black, #581120.
Is #af223f a web-safe color?
No. The nearest web-safe colour is #993333, ΔE2000 6.5 away. The palette only matters for legacy displays and some email clients now.
What does the color #af223f mean?
As a red, it reads urgent, appetising, bold. Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing. At this chroma the effect is amplified — it will dominate whatever sits beside it.
What gradient works with #af223f?
The safest is same-hue elevation: linear-gradient(135deg, #D83657, #af223f 45%, #6B1526). For more colour, a short hue run to #955F1D keeps it rich without turning muddy.
