}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 #F05430 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: #f05430 as text on that neutral, and that neutral as text on #f05430.

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. #f05430 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.
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.

#f05430, answered
What color is #f05430?
#f05430 is a balanced electric red, closest to Orange Red (ΔE2000 4.8). It sits at 11° on the hue wheel with 87% saturation and 57% lightness, which reads as warm.
What is the RGB value of #f05430?
rgb(240, 84, 48) — 240 red, 84 green and 48 blue out of 255, or 94.1% / 32.9% / 18.8% by channel.
What is #f05430 in HSL and HSV?
hsl(11, 87%, 57%) and hsv(11, 80%, 94%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #f05430 a light or a dark color?
It is a mid-tone. Relative luminance is 0.2508 and perceived brightness is 58%, so black text on it reaches 6.02:1.
Should I use black or white text on #f05430?
Black. It scores 6.02:1 against #f05430, versus 3.49:1 for white — AA at any size.
Is #f05430 accessible on a white background?
#f05430 on white scores 3.49:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #DD3710 to reach 4.5:1, or #A4290C for 7:1.
What is the complementary color of #f05430?
#30CCF0 sits directly opposite on the wheel. Softer options are the split-complements #30F0B4 and #306CF0, which give the same contrast with far less vibration.
What colors go well with #f05430?
For interface work: #FAF5F4 as the surface, #EDC8C0 for borders, #9B5A4B for secondary text, #0AC2B7 as an accent and #771D09 for hover and pressed states. For a palette, the analogous pair #F0306C and #F0B430 stays calm, while #30CCF0 is the loudest partner.
What is #f05430 in CMYK for printing?
cmyk(0%, 65%, 80%, 6%). 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 #f05430 warm or cool?
Warm — it scores 10 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F06D30; nudged cooler, #F22E51.
Which Tailwind color is closest to #f05430?
The red family — its 500 step is #ef4444, ΔE2000 7.9 away. That is a visible difference, so define #f05430 as a custom token rather than reaching for the built-in.
How do I use #f05430 in Tailwind CSS?
Inline it as an arbitrary value with bg-[#f05430] or text-[#f05430], 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 #f05430 with 50% opacity?
rgba(240, 84, 48, 0.5), or #f0543080 in eight-digit hex. Over white that composites to #F8AA98; over black, #782A18.
Is #f05430 a web-safe color?
No. The nearest web-safe colour is #FF6633, ΔE2000 5.5 away. The palette only matters for legacy displays and some email clients now.
What does the color #f05430 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 #f05430?
The safest is same-hue elevation: linear-gradient(135deg, #F48369, #f05430 45%, #771D09). For more colour, a short hue run to #EEE014 keeps it rich without turning muddy.
