Meaning and mood

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

friendlyenergeticaffordablesocial

Orange is red with the aggression taken out — approachable, active, and strongly associated with buying and doing.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The low lightness adds weight and formality.

Worth knowing

Hard to make feel premium, and it collides with the "caution" band in status systems.

Transparency

What each alpha value actually composites to. The top row is #a45430 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.

#a45430, answered

What color is #a45430?

#a45430 is a dark vivid orange, closest to Sienna (ΔE2000 1.1). It sits at 19° on the hue wheel with 55% saturation and 42% lightness, which reads as warm.

What is the RGB value of #a45430?

rgb(164, 84, 48) — 164 red, 84 green and 48 blue out of 255, or 64.3% / 32.9% / 18.8% by channel.

What is #a45430 in HSL and HSV?

hsl(19, 55%, 42%) and hsv(19, 71%, 64%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #a45430 a light or a dark color?

It is a dark color. Relative luminance is 0.1445 and perceived brightness is 44%, so white text on it reaches 5.40:1.

Should I use black or white text on #a45430?

White. It scores 5.40:1 against #a45430, versus 3.89:1 for black — AA at any size.

Is #a45430 accessible on a white background?

#a45430 on white scores 5.40:1, which clears AA at every size but not AAA.

What is the complementary color of #a45430?

#3080A4 sits directly opposite on the wheel. Softer options are the split-complements #30A48E and #3046A4, which give the same contrast with far less vibration.

What colors go well with #a45430?

For interface work: #FAF6F4 as the surface, #EDCEC0 for borders, #9B634B for secondary text, #2A9BA2 as an accent and #63321D for hover and pressed states. For a palette, the analogous pair #A43046 and #A48E30 stays calm, while #3080A4 is the loudest partner.

What is #a45430 in CMYK for printing?

cmyk(0%, 49%, 71%, 36%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #a45430 warm or cool?

Warm — it scores 6 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #B86836; nudged cooler, #A62E35.

Which Tailwind color is closest to #a45430?

The red family — its 500 step is #ef4444, ΔE2000 17.2 away. That is a visible difference, so define #a45430 as a custom token rather than reaching for the built-in.

How do I use #a45430 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#a45430] or text-[#a45430], 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 #a45430 with 50% opacity?

rgba(164, 84, 48, 0.5), or #a4543080 in eight-digit hex. Over white that composites to #D2AA98; over black, #522A18.

Is #a45430 a web-safe color?

No. The nearest web-safe colour is #996633, ΔE2000 10 away. The palette only matters for legacy displays and some email clients now.
