Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

expressiveyouthfulwarmconfident

Pink is the fastest way to signal that a product is not another enterprise dashboard. It carries beauty, fashion and culture brands.

At this chroma the association is amplified — it will dominate anything placed beside it, so give it space and use it sparingly. The low lightness adds weight and formality.

Worth knowing

Strong gendered associations in some markets — test it with the audience you actually have.

#910a39, answered

What color is #910a39?

#910a39 is a dark electric magenta / pink, closest to Brown (ΔE2000 12). It sits at 339° on the hue wheel with 87% saturation and 30% lightness, which reads as warm.

What is the RGB value of #910a39?

rgb(145, 10, 57) — 145 red, 10 green and 57 blue out of 255, or 56.9% / 3.9% / 22.4% by channel.

What is #910a39 in HSL and HSV?

hsl(339, 87%, 30%) and hsv(339, 93%, 57%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #910a39 a light or a dark color?

It is a dark color. Relative luminance is 0.0653 and perceived brightness is 32%, so white text on it reaches 9.10:1.

Should I use black or white text on #910a39?

White. It scores 9.10:1 against #910a39, versus 2.31:1 for black — AAA at any size.

Is #910a39 accessible on a white background?

#910a39 on white scores 9.10:1, which clears AAA at every size.

What is the complementary color of #910a39?

#0A9162 sits directly opposite on the wheel. Softer options are the split-complements #0A911E and #0A7D91, which give the same contrast with far less vibration.

What colors go well with #910a39?

For interface work: #FAF4F6 as the surface, #EDC0CF for borders, #9B4B67 for secondary text, #079440 as an accent and #77082F for hover and pressed states. For a palette, the analogous pair #910A7D and #911E0A stays calm, while #0A9162 is the loudest partner.

What is #910a39 in CMYK for printing?

cmyk(0%, 93%, 61%, 43%). 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 #910a39 warm or cool?

Warm — it scores 28 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #910C0A; nudged cooler, #93086B.

Which Tailwind color is closest to #910a39?

The rose family — its 500 step is #f43f5e, ΔE2000 23.9 away. That is a visible difference, so define #910a39 as a custom token rather than reaching for the built-in.

How do I use #910a39 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#910a39] or text-[#910a39], 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 #910a39 with 50% opacity?

rgba(145, 10, 57, 0.5), or #910a3980 in eight-digit hex. Over white that composites to #C8859C; over black, #49051D.

Is #910a39 a web-safe color?
