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 lightness keeps it airy and approachable.

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 #6f5af5 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.

#6f5af5, answered

What color is #6f5af5?

#6f5af5 is a light electric blue, closest to Medium Slate Blue (ΔE2000 4.3). It sits at 248° on the hue wheel with 89% saturation and 66% lightness, which reads as cool.

What is the RGB value of #6f5af5?

rgb(111, 90, 245) — 111 red, 90 green and 245 blue out of 255, or 43.5% / 35.3% / 96.1% by channel.

What is #6f5af5 in HSL and HSV?

hsl(248, 89%, 66%) and hsv(248, 63%, 96%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #6f5af5 a light or a dark color?

It is a dark color. Relative luminance is 0.1728 and perceived brightness is 48%, so white text on it reaches 4.71:1.

Should I use black or white text on #6f5af5?

White. It scores 4.71:1 against #6f5af5, versus 4.46:1 for black — AA at any size.

Is #6f5af5 accessible on a white background?

#6f5af5 on white scores 4.71:1, which clears AA at every size but not AAA.

What is the complementary color of #6f5af5?

#E0F55A sits directly opposite on the wheel. Softer options are the split-complements #F5BC5A and #93F55A, which give the same contrast with far less vibration.

What colors go well with #6f5af5?

For interface work: #F5F4FA as the surface, #C6C0ED for borders, #554B9B for secondary text, #C5AF07 as an accent and #170778 for hover and pressed states. For a palette, the analogous pair #5A93F5 and #BC5AF5 stays calm, while #E0F55A is the loudest partner.

What is #6f5af5 in CMYK for printing?

cmyk(55%, 63%, 0%, 4%). 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 #6f5af5 warm or cool?

Cool — it scores 79 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #A85AF5; nudged cooler, #587AF7.

Which Tailwind color is closest to #6f5af5?

The indigo family — its 500 step is #6366f1, ΔE2000 4.1 away. That is a visible difference, so define #6f5af5 as a custom token rather than reaching for the built-in.

How do I use #6f5af5 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#6f5af5] or text-[#6f5af5], 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 #6f5af5 with 50% opacity?

rgba(111, 90, 245, 0.5), or #6f5af580 in eight-digit hex. Over white that composites to #B7ADFA; over black, #382D7B.

Is #6f5af5 a web-safe color?

No. The nearest web-safe colour is #6666FF, ΔE2000 4.1 away. The palette only matters for legacy displays and some email clients now.

What does the color #6f5af5 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 #6f5af5?
