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.

What each alpha value actually composites to. The top row is #086bc9 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.

#086bc9, answered

What color is #086bc9?

#086bc9 is a dark electric blue, closest to Royal Blue (ΔE2000 6.9). It sits at 209° on the hue wheel with 92% saturation and 41% lightness, which reads as cool.

What is the RGB value of #086bc9?

rgb(8, 107, 201) — 8 red, 107 green and 201 blue out of 255, or 3.1% / 42% / 78.8% by channel.

What is #086bc9 in HSL and HSV?

hsl(209, 92%, 41%) and hsv(209, 96%, 79%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #086bc9 a light or a dark color?

It is a dark color. Relative luminance is 0.1478 and perceived brightness is 42%, so white text on it reaches 5.31:1.

Should I use black or white text on #086bc9?

White. It scores 5.31:1 against #086bc9, versus 3.96:1 for black — AA at any size.

Is #086bc9 accessible on a white background?

#086bc9 on white scores 5.31:1, which clears AA at every size but not AAA.

What is the complementary color of #086bc9?

#C96608 sits directly opposite on the wheel. Softer options are the split-complements #C9080B and #C9C608, which give the same contrast with far less vibration.

What colors go well with #086bc9?

For interface work: #F4F7FA as the surface, #C0D7ED for borders, #4B749B for secondary text, #CD3404 as an accent and #05417B for hover and pressed states. For a palette, the analogous pair #08C9C6 and #080BC9 stays calm, while #C96608 is the loudest partner.

What is #086bc9 in CMYK for printing?

cmyk(96%, 47%, 0%, 21%). 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 #086bc9 warm or cool?

Cool — it scores 100 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #0824C9; nudged cooler, #055AB2.

Which Tailwind color is closest to #086bc9?

The blue family — its 500 step is #3b82f6, ΔE2000 10.5 away. That is a visible difference, so define #086bc9 as a custom token rather than reaching for the built-in.

How do I use #086bc9 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#086bc9] or text-[#086bc9], 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 #086bc9 with 50% opacity?

rgba(8, 107, 201, 0.5), or #086bc980 in eight-digit hex. Over white that composites to #84B5E4; over black, #043665.

Is #086bc9 a web-safe color?

No. The nearest web-safe colour is #0066CC, ΔE2000 1.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #086bc9 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 #086bc9?
