Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

How to use #ada042

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

Works well for
  • Text and icons on dark surfaces
  • Charts, tags and secondary surfaces
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Text of any size on white — fails WCAG AA
  • Thin strokes and 1px borders — they disappear on light UI
  • Pairing with a same-lightness hue — edges vibrate
Minimum size as text on white
Not as text
Safe as a fill behind white type
No — use #5C5523
Safe as a 1px border on white
No — use #A2963E

Meaning and mood

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

optimisticalertcheap-and-cheerfulvisible

The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail.

The muted chroma softens the association — it reads considered rather than loud, which suits long-form and data-heavy screens. The mid lightness keeps it versatile in both themes.

Worth knowing

Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

Transparency

What each alpha value actually composites to. The top row is #ada042 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.

#ada042, answered

What color is #ada042?

#ada042 is a balanced soft yellow, closest to Dark Khaki (ΔE2000 7.5). It sits at 53° on the hue wheel with 45% saturation and 47% lightness, which reads as warm.

What is the RGB value of #ada042?

rgb(173, 160, 66) — 173 red, 160 green and 66 blue out of 255, or 67.8% / 62.7% / 25.9% by channel.

What is #ada042 in HSL and HSV?

hsl(53, 45%, 47%) and hsv(53, 62%, 68%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #ada042 a light or a dark color?

It is a mid-tone. Relative luminance is 0.3442 and perceived brightness is 61%, so black text on it reaches 7.88:1.

Should I use black or white text on #ada042?

Black. It scores 7.88:1 against #ada042, versus 2.66:1 for white — AAA at any size.

Is #ada042 accessible on a white background?

#ada042 on white scores 2.66:1, which fails WCAG AA at every size. Darken it to #817731 to reach 4.5:1, or #605824 for 7:1.

What is the complementary color of #ada042?

#424FAD sits directly opposite on the wheel. Softer options are the split-complements #4285AD and #6B42AD, which give the same contrast with far less vibration.

What colors go well with #ada042?

For interface work: #FAFAF4 as the surface, #E8E4C4 for borders, #9B914B for secondary text, #3D69B2 as an accent and #5C5523 for hover and pressed states. For a palette, the analogous pair #AD6B42 and #85AD42 stays calm, while #424FAD is the loudest partner.

What is #ada042 in CMYK for printing?

cmyk(0%, 8%, 62%, 32%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #ada042 warm or cool?

Warm — it scores 19 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #AD7F42; nudged cooler, #94B040.

Which Tailwind color is closest to #ada042?

The yellow family — its 500 step is #eab308, ΔE2000 14.4 away. That is a visible difference, so define #ada042 as a custom token rather than reaching for the built-in.

How do I use #ada042 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#ada042] or text-[#ada042], 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 #ada042 with 50% opacity?

rgba(173, 160, 66, 0.5), or #ada04280 in eight-digit hex. Over white that composites to #D6D0A1; over black, #575021.

Is #ada042 a web-safe color?

No. The nearest web-safe colour is #999933, ΔE2000 4.9 away. The palette only matters for legacy displays and some email clients now.

What does the color #ada042 mean?

As a yellow, it reads optimistic, alert, cheap-and-cheerful. The most visible hue at low light levels, which is why it owns warnings, hazard tape and value retail. At this moderate chroma the association is present but not shouted.

What gradient works with #ada042?

The safest is same-hue elevation: linear-gradient(135deg, #C5BA67, #ada042 45%, #5C5523). For more colour, a short hue run to #5C973A keeps it rich without turning muddy.
