How to use #751c01

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

Works well for
  • Body text and links on white
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Headers, footers and dark-mode surfaces
  • Brand accents, badges and data highlights
Use with care
  • Text on black or near-black surfaces
  • Full-page backgrounds — tiring over long sessions
  • Black text placed on it
  • 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

Safe as a fill behind white type

Safe as a 1px border on white

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.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

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.

Transparency

What each alpha value actually composites to. The top row is #751c01 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.

#751c01, answered

What color is #751c01?

#751c01 is a deep electric red, closest to Maroon (ΔE2000 4.5). It sits at 14° on the hue wheel with 98% saturation and 23% lightness, which reads as warm.

What is the RGB value of #751c01?

rgb(117, 28, 1) — 117 red, 28 green and 1 blue out of 255, or 45.9% / 11% / 0.4% by channel.

What is #751c01 in HSL and HSV?

hsl(14, 98%, 23%) and hsv(14, 99%, 46%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #751c01 a light or a dark color?

It is a dark color. Relative luminance is 0.0461 and perceived brightness is 26%, so white text on it reaches 10.92:1.

Should I use black or white text on #751c01?

White. It scores 10.92:1 against #751c01, versus 1.92:1 for black — AAA at any size.

Is #751c01 accessible on a white background?

#751c01 on white scores 10.92:1, which clears AAA at every size.

What is the complementary color of #751c01?

#015A75 sits directly opposite on the wheel. Softer options are the split-complements #017556 and #012075, which give the same contrast with far less vibration.

What colors go well with #751c01?

For interface work: #FAF6F4 as the surface, #EDCAC0 for borders, #9B5D4B for secondary text, #007674 as an accent and #7E1E01 for hover and pressed states. For a palette, the analogous pair #750120 and #755601 stays calm, while #015A75 is the loudest partner.

What is #751c01 in CMYK for printing?

cmyk(0%, 76%, 99%, 54%). 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 #751c01 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 #752B01; nudged cooler, #760010.

Which Tailwind color is closest to #751c01?

The red family — its 500 step is #ef4444, ΔE2000 28 away. That is a visible difference, so define #751c01 as a custom token rather than reaching for the built-in.

How do I use #751c01 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#751c01] or text-[#751c01], 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 #751c01 with 50% opacity?

rgba(117, 28, 1, 0.5), or #751c0180 in eight-digit hex. Over white that composites to #BA8E80; over black, #3B0E01.

Is #751c01 a web-safe color?

No. The nearest web-safe colour is #663300, ΔE2000 10.8 away. The palette only matters for legacy displays and some email clients now.
