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.

What each alpha value actually composites to. The top row is #786daf 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.

#786daf, answered

What color is #786daf?

#786daf is a balanced soft blue, closest to Medium Purple (ΔE2000 8.8). It sits at 250° on the hue wheel with 29% saturation and 56% lightness, which reads as cool.

What is the RGB value of #786daf?

rgb(120, 109, 175) — 120 red, 109 green and 175 blue out of 255, or 47.1% / 42.7% / 68.6% by channel.

What is #786daf in HSL and HSV?

hsl(250, 29%, 56%) and hsv(250, 38%, 69%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #786daf a light or a dark color?

It is a mid-tone. Relative luminance is 0.1803 and perceived brightness is 48%, so black text on it reaches 4.61:1.

Should I use black or white text on #786daf?

Black. It scores 4.61:1 against #786daf, versus 4.56:1 for white — AA at any size.

Is #786daf accessible on a white background?

#786daf on white scores 4.56:1, which clears AA at every size but not AAA.

What is the complementary color of #786daf?

#A4AF6D sits directly opposite on the wheel. Softer options are the split-complements #AF996D and #83AF6D, which give the same contrast with far less vibration.

What colors go well with #786daf?

For interface work: #F6F5FA as the surface, #CECAE2 for borders, #5C5194 for secondary text, #888244 as an accent and #332D52 for hover and pressed states. For a palette, the analogous pair #6D83AF and #996DAF stays calm, while #A4AF6D is the loudest partner.

What is #786daf in CMYK for printing?

cmyk(31%, 38%, 0%, 31%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #786daf warm or cool?

Cool — it scores 73 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #906DAF; nudged cooler, #6B79B1.

Which Tailwind color is closest to #786daf?

The slate family — its 500 step is #64748b, ΔE2000 10.5 away. That is a visible difference, so define #786daf as a custom token rather than reaching for the built-in.

How do I use #786daf in Tailwind CSS?

Inline it as an arbitrary value with bg-[#786daf] or text-[#786daf], 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 #786daf with 50% opacity?

rgba(120, 109, 175, 0.5), or #786daf80 in eight-digit hex. Over white that composites to #BCB6D7; over black, #3C3758.

Is #786daf a web-safe color?

No. The nearest web-safe colour is #666699, ΔE2000 5.5 away. The palette only matters for legacy displays and some email clients now.

What does the color #786daf 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 moderate chroma the association is present but not shouted.

What gradient works with #786daf?

The safest is same-hue elevation: linear-gradient(135deg, #9D95C5, #786daf 45%, #332D52). For more colour, a short hue run to #9E5AA4 keeps it rich without turning muddy.
