}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 #FF072F 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: #ff072f as text on that neutral, and that neutral as text on #ff072f.

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. #ff072f is pinned to step 600; 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.
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.
It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

#ff072f, answered
What color is #ff072f?
#ff072f is a balanced electric red, closest to Red (ΔE2000 6.8). It sits at 350° on the hue wheel with 100% saturation and 51% lightness, which reads as warm.
What is the RGB value of #ff072f?
rgb(255, 7, 47) — 255 red, 7 green and 47 blue out of 255, or 100% / 2.7% / 18.4% by channel.
What is #ff072f in HSL and HSV?
hsl(350, 100%, 51%) and hsv(350, 97%, 100%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #ff072f a light or a dark color?
It is a mid-tone. Relative luminance is 0.2162 and perceived brightness is 55%, so black text on it reaches 5.32:1.
Should I use black or white text on #ff072f?
Black. It scores 5.32:1 against #ff072f, versus 3.94:1 for white — AA at any size.
Is #ff072f accessible on a white background?
#ff072f on white scores 3.94:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #ED0026 to reach 4.5:1, or #B5001D for 7:1.
What is the complementary color of #ff072f?
#07FFD7 sits directly opposite on the wheel. Softer options are the split-complements #07FF5B and #07ABFF, which give the same contrast with far less vibration.
What colors go well with #ff072f?
For interface work: #FAF4F5 as the surface, #EDC0C7 for borders, #9B4B58 for secondary text, #00CC78 as an accent and #800015 for hover and pressed states. For a palette, the analogous pair #FF07AB and #FF5B07 stays calm, while #07FFD7 is the loudest partner.
What is #ff072f in CMYK for printing?
cmyk(0%, 97%, 82%, 0%). 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 #ff072f warm or cool?
Warm — it scores 22 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #FF2807; nudged cooler, #FF078A.
Which Tailwind color is closest to #ff072f?
The red family — its 500 step is #ef4444, ΔE2000 4.2 away. That is a visible difference, so define #ff072f as a custom token rather than reaching for the built-in.
How do I use #ff072f in Tailwind CSS?
Inline it as an arbitrary value with bg-[#ff072f] or text-[#ff072f], 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 #ff072f with 50% opacity?
rgba(255, 7, 47, 0.5), or #ff072f80 in eight-digit hex. Over white that composites to #FF8397; over black, #800418.
Is #ff072f a web-safe color?
No. The nearest web-safe colour is #FF0033, ΔE2000 1.1 away. The palette only matters for legacy displays and some email clients now.
What does the color #ff072f 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 #ff072f?
The safest is same-hue elevation: linear-gradient(135deg, #FF4463, #ff072f 45%, #800015). For more colour, a short hue run to #E88800 keeps it rich without turning muddy.
