How to use #700d21

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
Any size
Safe as a fill behind white type
Yes
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 #700d21 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.

#700d21, answered

What color is #700d21?

#700d21 is a deep electric red, closest to Maroon (ΔE2000 10.7). It sits at 348° on the hue wheel with 79% saturation and 25% lightness, which reads as warm.

What is the RGB value of #700d21?

rgb(112, 13, 33) — 112 red, 13 green and 33 blue out of 255, or 43.9% / 5.1% / 12.9% by channel.

What is #700d21 in HSL and HSV?

hsl(348, 79%, 25%) and hsv(348, 88%, 44%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #700d21 a light or a dark color?

It is a dark color. Relative luminance is 0.0384 and perceived brightness is 25%, so white text on it reaches 11.87:1.

Should I use black or white text on #700d21?

White. It scores 11.87:1 against #700d21, versus 1.77:1 for black — AAA at any size.

Is #700d21 accessible on a white background?

#700d21 on white scores 11.87:1, which clears AAA at every size.

What is the complementary color of #700d21?

#0D705C sits directly opposite on the wheel. Softer options are the split-complements #0D702B and #0D5270, which give the same contrast with far less vibration.

What colors go well with #700d21?

For interface work: #FAF4F6 as the surface, #EDC0C9 for borders, #9B4B5B for secondary text, #0A7243 as an accent and #720D22 for hover and pressed states. For a palette, the analogous pair #700D52 and #702B0D stays calm, while #0D705C is the loudest partner.

What is #700d21 in CMYK for printing?

cmyk(0%, 88%, 71%, 56%). 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 #700d21 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 #701D0D; nudged cooler, #710C45.

Which Tailwind color is closest to #700d21?

The red family — its 500 step is #ef4444, ΔE2000 29.4 away. That is a visible difference, so define #700d21 as a custom token rather than reaching for the built-in.

How do I use #700d21 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#700d21] or text-[#700d21], 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 #700d21 with 50% opacity?

rgba(112, 13, 33, 0.5), or #700d2180 in eight-digit hex. Over white that composites to #B88690; over black, #380711.

Is #700d21 a web-safe color?
