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.

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 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 #116eb8 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.

#116eb8, answered

What color is #116eb8?

#116eb8 is a dark electric blue, closest to Steel Blue (ΔE2000 7.8). It sits at 207° on the hue wheel with 83% saturation and 39% lightness, which reads as cool.

What is the RGB value of #116eb8?

rgb(17, 110, 184) — 17 red, 110 green and 184 blue out of 255, or 6.7% / 43.1% / 72.2% by channel.

What is #116eb8 in HSL and HSV?

hsl(207, 83%, 39%) and hsv(207, 91%, 72%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #116eb8 a light or a dark color?

It is a dark color. Relative luminance is 0.1473 and perceived brightness is 41%, so white text on it reaches 5.32:1.

Should I use black or white text on #116eb8?

White. It scores 5.32:1 against #116eb8, versus 3.95:1 for black — AA at any size.

Is #116eb8 accessible on a white background?

#116eb8 on white scores 5.32:1, which clears AA at every size but not AAA.

What is the complementary color of #116eb8?

#B85B11 sits directly opposite on the wheel. Softer options are the split-complements #B8111A and #B8AE11, which give the same contrast with far less vibration.

What colors go well with #116eb8?

For interface work: #F4F8FA as the surface, #C0D9ED for borders, #4B779B for secondary text, #BC2F0D as an accent and #0B4675 for hover and pressed states. For a palette, the analogous pair #11B8AE and #111AB8 stays calm, while #B85B11 is the loudest partner.

What is #116eb8 in CMYK for printing?

cmyk(91%, 40%, 0%, 28%). 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 #116eb8 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 #1131B8; nudged cooler, #0D59A2.

Which Tailwind color is closest to #116eb8?

The blue family — its 500 step is #3b82f6, ΔE2000 11.3 away. That is a visible difference, so define #116eb8 as a custom token rather than reaching for the built-in.

How do I use #116eb8 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#116eb8] or text-[#116eb8], 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 #116eb8 with 50% opacity?

rgba(17, 110, 184, 0.5), or #116eb880 in eight-digit hex. Over white that composites to #88B7DC; over black, #09375C.

Is #116eb8 a web-safe color?

No. The nearest web-safe colour is #0066CC, ΔE2000 4.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #116eb8 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.
