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.

How to use #74acda

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

Works well for
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #1B4365
Safe as a 1px border on white
No — use #5499D1

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

trustedcalmcompetentcorporate

The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The lightness keeps it airy and approachable.

Worth knowing

It is also the most crowded hue on the web. Distinctiveness has to come from your other choices.

Transparency

What each alpha value actually composites to. The top row is #74acda 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.

#74acda, answered

What color is #74acda?

#74acda is a light vivid blue, closest to Cornflower Blue (ΔE2000 8). It sits at 207° on the hue wheel with 58% saturation and 66% lightness, which reads as cool.

What is the RGB value of #74acda?

rgb(116, 172, 218) — 116 red, 172 green and 218 blue out of 255, or 45.5% / 67.5% / 85.5% by channel.

What is #74acda in HSL and HSV?

hsl(207, 58%, 66%) and hsv(207, 47%, 85%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #74acda a light or a dark color?

It is a mid-tone. Relative luminance is 0.3828 and perceived brightness is 64%, so black text on it reaches 8.66:1.

Should I use black or white text on #74acda?

Black. It scores 8.66:1 against #74acda, versus 2.43:1 for white — AAA at any size.

Is #74acda accessible on a white background?

#74acda on white scores 2.43:1, which fails WCAG AA at every size. Darken it to #317BB7 to reach 4.5:1, or #245A87 for 7:1.

What is the complementary color of #74acda?

#DAA274 sits directly opposite on the wheel. Softer options are the split-complements #DA7479 and #DAD574, which give the same contrast with far less vibration.

What colors go well with #74acda?

For interface work: #F4F8FA as the surface, #C0D8ED for borders, #4B779B for secondary text, #A64026 as an accent and #1B4365 for hover and pressed states. For a palette, the analogous pair #74DAD5 and #7479DA stays calm, while #DAA274 is the loudest partner.

What is #74acda in CMYK for printing?

cmyk(47%, 21%, 0%, 15%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #74acda warm or cool?

Cool — it scores 99 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #7487DA; nudged cooler, #5E9AD7.

Which Tailwind color is closest to #74acda?

The sky family — its 500 step is #0ea5e9, ΔE2000 7.3 away. That is a visible difference, so define #74acda as a custom token rather than reaching for the built-in.

How do I use #74acda in Tailwind CSS?

Inline it as an arbitrary value with bg-[#74acda] or text-[#74acda], 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 #74acda with 50% opacity?

rgba(116, 172, 218, 0.5), or #74acda80 in eight-digit hex. Over white that composites to #BAD6ED; over black, #3A566D.

Is #74acda a web-safe color?

No. The nearest web-safe colour is #6699CC, ΔE2000 5.8 away. The palette only matters for legacy displays and some email clients now.

What does the color #74acda mean?

As a blue, it reads trusted, calm, competent. The default of institutions for a reason: blue is read as stable and safe across nearly every culture that has been surveyed. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #74acda?

The safest is same-hue elevation: linear-gradient(135deg, #A4C9E7, #74acda 45%, #1B4365). For more colour, a short hue run to #745CD4 keeps it rich without turning muddy.
