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 #deee2e

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

Works well for
  • 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
  • Text of any size on white — fails WCAG AA
  • Full-page backgrounds — tiring over long sessions
  • 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 #6D760A
Safe as a 1px border on white
No — use #8E9A0D

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.

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

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 #deee2e 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.

#deee2e, answered

What color is #deee2e?

#deee2e is a balanced electric yellow, closest to Yellow (ΔE2000 6). It sits at 65° on the hue wheel with 85% saturation and 56% lightness, which reads as warm.

What is the RGB value of #deee2e?

rgb(222, 238, 46) — 222 red, 238 green and 46 blue out of 255, or 87.1% / 93.3% / 18% by channel.

What is #deee2e in HSL and HSV?

hsl(65, 85%, 56%) and hsv(65, 81%, 93%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #deee2e a light or a dark color?

It is a light color. Relative luminance is 0.7688 and perceived brightness is 86%, so black text on it reaches 16.38:1.

Should I use black or white text on #deee2e?

Black. It scores 16.38:1 against #deee2e, versus 1.28:1 for white — AAA at any size.

Is #deee2e accessible on a white background?

#deee2e on white scores 1.28:1, which fails WCAG AA at every size. Darken it to #70790A to reach 4.5:1, or #565D08 for 7:1.

What is the complementary color of #deee2e?

#3E2EEE sits directly opposite on the wheel. Softer options are the split-complements #2E7EEE and #9E2EEE, which give the same contrast with far less vibration.

What colors go well with #deee2e?

For interface work: #FAFAF4 as the surface, #E9EDC0 for borders, #949B4B for secondary text, #294BF3 as an accent and #6D760A for hover and pressed states. For a palette, the analogous pair #EE9E2E and #7EEE2E stays calm, while #3E2EEE is the loudest partner.

What is #deee2e in CMYK for printing?

cmyk(7%, 0%, 81%, 7%). 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 #deee2e warm or cool?

Warm — it scores 29 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #EEB82E; nudged cooler, #98F02C.

Which Tailwind color is closest to #deee2e?

The lime family — its 500 step is #84cc16, ΔE2000 14.4 away. That is a visible difference, so define #deee2e as a custom token rather than reaching for the built-in.

How do I use #deee2e in Tailwind CSS?

Inline it as an arbitrary value with bg-[#deee2e] or text-[#deee2e], 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 #deee2e with 50% opacity?

rgba(222, 238, 46, 0.5), or #deee2e80 in eight-digit hex. Over white that composites to #EFF797; over black, #6F7717.

Is #deee2e a web-safe color?

No. The nearest web-safe colour is #CCFF33, ΔE2000 6.4 away. The palette only matters for legacy displays and some email clients now.

What does the color #deee2e 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 chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #deee2e?

The safest is same-hue elevation: linear-gradient(135deg, #E7F367, #deee2e 45%, #6D760A). For more colour, a short hue run to #37EA13 keeps it rich without turning muddy.
