#cf3b3d
a balanced, vivid red · warm · closest name: Crimson
Token name suggestion: Studio Cherry
#cf3b3d is a balanced vivid red, 359° on the wheel and 17/100 on the cool side. Put white text on it (4.83:1). As text it scores 4.83:1 on white — safe at any size. Nearest name is Crimson, nearest Tailwind family is red.
At a glance
Every number on this page in one read: what #cf3b3d is made of, how bright it looks, and which way it leans.
Left edge is grey, right edge is full chroma; top is white, bottom is black. The dot is #cf3b3d.
Reads warm. Warm and cool siblings keep the same lightness, so you can swap one in without redoing your contrast maths.
Green carries most of what the eye calls brightness — that is why WCAG weights it 0.7152.

}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 #CF3B3D 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: #cf3b3d as text on that neutral, and that neutral as text on #cf3b3d.

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. #cf3b3d is pinned to step 500; 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 mid lightness keeps it versatile in both themes.
It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

#cf3b3d, answered
What color is #cf3b3d?
#cf3b3d is a balanced vivid red, closest to Crimson (ΔE2000 4.3). It sits at 359° on the hue wheel with 61% saturation and 52% lightness, which reads as warm.
What is the RGB value of #cf3b3d?
rgb(207, 59, 61) — 207 red, 59 green and 61 blue out of 255, or 81.2% / 23.1% / 23.9% by channel.
What is #cf3b3d in HSL and HSV?
hsl(359, 61%, 52%) and hsv(359, 71%, 81%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #cf3b3d a light or a dark color?
It is a dark color. Relative luminance is 0.1673 and perceived brightness is 48%, so white text on it reaches 4.83:1.
Should I use black or white text on #cf3b3d?
White. It scores 4.83:1 against #cf3b3d, versus 4.35:1 for black — AA at any size.
Is #cf3b3d accessible on a white background?
#cf3b3d on white scores 4.83:1, which clears AA at every size but not AAA.
What is the complementary color of #cf3b3d?
#3BCFCD sits directly opposite on the wheel. Softer options are the split-complements #3BCF83 and #3B87CF, which give the same contrast with far less vibration.
What colors go well with #cf3b3d?
For interface work: #FAF4F4 as the surface, #EDC0C0 for borders, #9B4B4C for secondary text, #24A885 as an accent and #66191A for hover and pressed states. For a palette, the analogous pair #CF3B87 and #CF833B stays calm, while #3BCFCD is the loudest partner.
What is #cf3b3d in CMYK for printing?
cmyk(0%, 72%, 71%, 19%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.
Is #cf3b3d warm or cool?
Warm — it scores 17 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #CF613B; nudged cooler, #D23973.
Which Tailwind color is closest to #cf3b3d?
The red family — its 500 step is #ef4444, ΔE2000 7.4 away. That is a visible difference, so define #cf3b3d as a custom token rather than reaching for the built-in.
How do I use #cf3b3d in Tailwind CSS?
Inline it as an arbitrary value with bg-[#cf3b3d] or text-[#cf3b3d], 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 #cf3b3d with 50% opacity?
rgba(207, 59, 61, 0.5), or #cf3b3d80 in eight-digit hex. Over white that composites to #E79D9E; over black, #681E1F.
Is #cf3b3d a web-safe color?
No. The nearest web-safe colour is #CC3333, ΔE2000 2.3 away. The palette only matters for legacy displays and some email clients now.
What does the color #cf3b3d 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 #cf3b3d?
The safest is same-hue elevation: linear-gradient(135deg, #DB6C6E, #cf3b3d 45%, #66191A). For more colour, a short hue run to #BD982E keeps it rich without turning muddy.
