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.

#082f90, answered

What color is #082f90?

#082f90 is a dark electric blue, closest to Midnight Blue (ΔE2000 7.6). It sits at 223° on the hue wheel with 90% saturation and 30% lightness, which reads as cool.

What is the RGB value of #082f90?

rgb(8, 47, 144) — 8 red, 47 green and 144 blue out of 255, or 3.1% / 18.4% / 56.5% by channel.

What is #082f90 in HSL and HSV?

hsl(223, 90%, 30%) and hsv(223, 94%, 56%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #082f90 a light or a dark color?

It is a dark color. Relative luminance is 0.0410 and perceived brightness is 24%, so white text on it reaches 11.54:1.

Should I use black or white text on #082f90?

White. It scores 11.54:1 against #082f90, versus 1.82:1 for black — AAA at any size.

Is #082f90 accessible on a white background?

#082f90 on white scores 11.54:1, which clears AAA at every size.

What is the complementary color of #082f90?

#906908 sits directly opposite on the wheel. Softer options are the split-complements #902508 and #739008, which give the same contrast with far less vibration.

What colors go well with #082f90?

For interface work: #F4F6FA as the surface, #C0CDED for borders, #4B629B for secondary text, #934705 as an accent and #072779 for hover and pressed states. For a palette, the analogous pair #087390 and #250890 stays calm, while #906908 is the loudest partner.

What is #082f90 in CMYK for printing?

cmyk(94%, 67%, 0%, 44%). 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 #082f90 warm or cool?

Cool — it scores 93 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #130890; nudged cooler, #063D92.

Which Tailwind color is closest to #082f90?

The indigo family — its 500 step is #6366f1, ΔE2000 22.4 away. That is a visible difference, so define #082f90 as a custom token rather than reaching for the built-in.

How do I use #082f90 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#082f90] or text-[#082f90], 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 #082f90 with 50% opacity?

rgba(8, 47, 144, 0.5), or #082f9080 in eight-digit hex. Over white that composites to #8497C8; over black, #041848.

Is #082f90 a web-safe color?
