#ddf126
a balanced, electric yellow · warm · closest name: Yellow
Token name suggestion: Signal Straw
#ddf126 is a balanced electric yellow, 66° on the wheel and 30/100 on the cool side. Put black text on it (16.68:1). As text it scores 1.26:1 on white — use #707B08 instead. Nearest name is Yellow, nearest Tailwind family is lime.
At a glance
Every number on this page in one read: what #ddf126 is made of, how bright it looks, and which way it leans.
Left edge is grey, right edge is full chroma; top is white, bottom is black. The dot is #ddf126.
Reads warm. Warm and cool siblings keep the same lightness, so you can swap one in without redoing your contrast maths.
Green carries most of what the eye calls brightness — that is why WCAG weights it 0.7152.

}Best text color
Only one of black and white can be right. This is the one, with the number that proves it.
Make it accessible
A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.
Large text — 24px regular or 18.66px bold and above — only needs 3:1, so #8E9D0A is enough for headings on white. Non-text elements such as icons, chart strokes and focus rings also sit at 3:1 under WCAG 2.2 (1.4.11).
Accessibility — WCAG contrast
Contrast is symmetric, so each row covers both directions: #ddf126 as text on that neutral, and that neutral as text on #ddf126.

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.
Color scale — 50 to 950
A Tailwind-shaped ramp built around this exact hex. #ddf126 is pinned to step 500; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
The same eleven steps expressed in OKLCH, where equal lightness numbers actually look equally spaced. HSL ramps go muddy in the yellows and washed out in the blues; this one does not. Modern browsers render it natively — the hex ramp above is the fallback.

Not a palette — a role sheet. Each swatch answers one question you will hit while building the component.
Surface, border, heading and body all derive from this one hue, so the screen stays coherent without a second palette.
Lightness flips, hue holds. The accent stays the anchor in both themes.

Meaning and mood
What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.
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.
Almost never passes contrast against white. Treat it as a surface or a marker, not as text.

#ddf126, answered
What color is #ddf126?
#ddf126 is a balanced electric yellow, closest to Yellow (ΔE2000 6). It sits at 66° on the hue wheel with 88% saturation and 55% lightness, which reads as warm.
What is the RGB value of #ddf126?
rgb(221, 241, 38) — 221 red, 241 green and 38 blue out of 255, or 86.7% / 94.5% / 14.9% by channel.
What is #ddf126 in HSL and HSV?
hsl(66, 88%, 55%) and hsv(66, 84%, 95%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.
Is #ddf126 a light or a dark color?
It is a light color. Relative luminance is 0.7842 and perceived brightness is 87%, so black text on it reaches 16.68:1.
Should I use black or white text on #ddf126?
Black. It scores 16.68:1 against #ddf126, versus 1.26:1 for white — AAA at any size.
Is #ddf126 accessible on a white background?
#ddf126 on white scores 1.26:1, which fails WCAG AA at every size. Darken it to #707B08 to reach 4.5:1, or #565E06 for 7:1.
What is the complementary color of #ddf126?
#3A26F1 sits directly opposite on the wheel. Softer options are the split-complements #2678F1 and #9F26F1, which give the same contrast with far less vibration.
What colors go well with #ddf126?
For interface work: #FAFAF4 as the surface, #E8EDC0 for borders, #939B4B for secondary text, #2142F6 as an accent and #6D7808 for hover and pressed states. For a palette, the analogous pair #F19F26 and #78F126 stays calm, while #3A26F1 is the loudest partner.
What is #ddf126 in CMYK for printing?
cmyk(8%, 0%, 84%, 6%). 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 #ddf126 warm or cool?
Warm — it scores 30 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #F1BB26; nudged cooler, #93F324.
Which Tailwind color is closest to #ddf126?
The lime family — its 500 step is #84cc16, ΔE2000 14.4 away. That is a visible difference, so define #ddf126 as a custom token rather than reaching for the built-in.
How do I use #ddf126 in Tailwind CSS?
Inline it as an arbitrary value with bg-[#ddf126] or text-[#ddf126], 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 #ddf126 with 50% opacity?
rgba(221, 241, 38, 0.5), or #ddf12680 in eight-digit hex. Over white that composites to #EEF893; over black, #6F7913.
Is #ddf126 a web-safe color?
No. The nearest web-safe colour is #CCFF33, ΔE2000 5.6 away. The palette only matters for legacy displays and some email clients now.
What does the color #ddf126 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 #ddf126?
The safest is same-hue elevation: linear-gradient(135deg, #E6F55F, #ddf126 45%, #6D7808). For more colour, a short hue run to #30E90F keeps it rich without turning muddy.
