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.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

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 #676c95 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.

#676c95, answered

What color is #676c95?

#676c95 is a balanced soft blue, closest to Slate Blue (ΔE2000 12.4). It sits at 234° on the hue wheel with 18% saturation and 49% lightness, which reads as cool.

What is the RGB value of #676c95?

rgb(103, 108, 149) — 103 red, 108 green and 149 blue out of 255, or 40.4% / 42.4% / 58.4% by channel.

What is #676c95 in HSL and HSV?

hsl(234, 18%, 49%) and hsv(233, 31%, 58%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #676c95 a light or a dark color?

It is a dark color. Relative luminance is 0.1578 and perceived brightness is 44%, so white text on it reaches 5.05:1.

Should I use black or white text on #676c95?

White. It scores 5.05:1 against #676c95, versus 4.16:1 for black — AA at any size.

Is #676c95 accessible on a white background?

#676c95 on white scores 5.05:1, which clears AA at every size but not AAA.

What is the complementary color of #676c95?

#959067 sits directly opposite on the wheel. Softer options are the split-complements #957967 and #839567, which give the same contrast with far less vibration.

What colors go well with #676c95?

For interface work: #F6F6F9 as the surface, #CFD0DE for borders, #5E6288 for secondary text, #9A8662 as an accent and #34374B for hover and pressed states. For a palette, the analogous pair #678395 and #796795 stays calm, while #959067 is the loudest partner.

What is #676c95 in CMYK for printing?

cmyk(31%, 28%, 0%, 42%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #676c95 warm or cool?

Cool — it scores 69 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #736795; nudged cooler, #647998.

Which Tailwind color is closest to #676c95?

The slate family — its 500 step is #64748b, ΔE2000 8.1 away. That is a visible difference, so define #676c95 as a custom token rather than reaching for the built-in.

How do I use #676c95 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#676c95] or text-[#676c95], 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 #676c95 with 50% opacity?

rgba(103, 108, 149, 0.5), or #676c9580 in eight-digit hex. Over white that composites to #B3B6CA; over black, #34364B.

Is #676c95 a web-safe color?

No. The nearest web-safe colour is #666699, ΔE2000 3 away. The palette only matters for legacy displays and some email clients now.
