How to use #196dfc

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

Works well for
  • Body text and links on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions
  • Pairing with a same-lightness hue — edges vibrate

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 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 #196dfc 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.

#196dfc, answered

What color is #196dfc?

#196dfc is a balanced electric blue, closest to Royal Blue (ΔE2000 3.7). It sits at 218° on the hue wheel with 97% saturation and 54% lightness, which reads as cool.

What is the RGB value of #196dfc?

rgb(25, 109, 252) — 25 red, 109 green and 252 blue out of 255, or 9.8% / 42.7% / 98.8% by channel.

What is #196dfc in HSL and HSV?

hsl(218, 97%, 54%) and hsv(218, 90%, 99%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #196dfc a light or a dark color?

It is a mid-tone. Relative luminance is 0.1817 and perceived brightness is 47%, so black text on it reaches 4.63:1.

Should I use black or white text on #196dfc?

Black. It scores 4.63:1 against #196dfc, versus 4.53:1 for white — AA at any size.

Is #196dfc accessible on a white background?

#196dfc on white scores 4.53:1, which clears AA at every size but not AAA.

What is the complementary color of #196dfc?

#FCA819 sits directly opposite on the wheel. Softer options are the split-complements #FC3619 and #DEFC19, which give the same contrast with far less vibration.

What colors go well with #196dfc?

For interface work: #F4F7FA as the surface, #C0D0ED for borders, #4B689B for secondary text, #CC4D00 as an accent and #02307E for hover and pressed states. For a palette, the analogous pair #19DEFC and #3619FC stays calm, while #FCA819 is the loudest partner.

What is #196dfc in CMYK for printing?

cmyk(90%, 57%, 0%, 1%). 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 #196dfc warm or cool?

Cool — it scores 96 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #191AFC; nudged cooler, #0169FB.

Which Tailwind color is closest to #196dfc?

The blue family — its 500 step is #3b82f6, ΔE2000 7.1 away. That is a visible difference, so define #196dfc as a custom token rather than reaching for the built-in.

How do I use #196dfc in Tailwind CSS?

Inline it as an arbitrary value with bg-[#196dfc] or text-[#196dfc], 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 #196dfc with 50% opacity?

rgba(25, 109, 252, 0.5), or #196dfc80 in eight-digit hex. Over white that composites to #8CB6FE; over black, #0D377E.

Is #196dfc a web-safe color?

No. The nearest web-safe colour is #0066FF, ΔE2000 2.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #196dfc 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 #196dfc?
