How to use #696cfb

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Headings from 24px up on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Card and section backgrounds
  • Brand accents, badges and data highlights
Use with care
  • Small text on white — under 4.5:1
  • Full-page backgrounds — tiring over long sessions
  • White text placed on it
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
24px / 18.66px bold
Safe as a fill behind white type
No — use #03067C
Safe as a 1px border on white
Yes

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.

#696cfb, answered

What color is #696cfb?

#696cfb is a light electric blue, closest to Medium Slate Blue (ΔE2000 3.7). It sits at 239° on the hue wheel with 95% saturation and 70% lightness, which reads as cool.

What is the RGB value of #696cfb?

rgb(105, 108, 251) — 105 red, 108 green and 251 blue out of 255, or 41.2% / 42.4% / 98.4% by channel.

What is #696cfb in HSL and HSV?

hsl(239, 95%, 70%) and hsv(239, 58%, 98%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #696cfb a light or a dark color?

It is a mid-tone. Relative luminance is 0.2069 and perceived brightness is 52%, so black text on it reaches 5.14:1.

Should I use black or white text on #696cfb?

Black. It scores 5.14:1 against #696cfb, versus 4.09:1 for white — AA at any size.

Is #696cfb accessible on a white background?

#696cfb on white scores 4.09:1, which only clears AA for large text — 18.66px bold or 24px regular and up. Darken it to #5F62FB to reach 4.5:1, or #2D31F9 for 7:1.

What is the complementary color of #696cfb?

#FBF869 sits directly opposite on the wheel. Softer options are the split-complements #FBAF69 and #B5FB69, which give the same contrast with far less vibration.

What colors go well with #696cfb?

For interface work: #F4F4FA as the surface, #C0C1ED for borders, #4B4C9B for secondary text, #CB9401 as an accent and #03067C for hover and pressed states. For a palette, the analogous pair #69B5FB and #AF69FB stays calm, while #FBF869 is the loudest partner.

What is #696cfb in CMYK for printing?

cmyk(58%, 57%, 0%, 2%). 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 #696cfb warm or cool?

Cool — it scores 84 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #9C69FB; nudged cooler, #6791FD.

Which Tailwind color is closest to #696cfb?

The indigo family — its 500 step is #6366f1, ΔE2000 2.5 away. That is close enough to swap in without anyone noticing.

How do I use #696cfb in Tailwind CSS?

Inline it as an arbitrary value with bg-[#696cfb] or text-[#696cfb], 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 #696cfb with 50% opacity?

rgba(105, 108, 251, 0.5), or #696cfb80 in eight-digit hex. Over white that composites to #B4B6FD; over black, #35367E.

Is #696cfb a web-safe color?
