About the Colordle color for September 21, 2026
Colordle #1641 was published on Monday, September 21, 2026. The daily puzzle resets at midnight in the player's local time, so the color you'd see on that calendar day depends on where you opened it.
The answer was Plum at hex code #66386A, decoding to RGB 102, 56, 106. That puts it in the purple family, which designers typically reach for when they need luxury goods, creative tools, and mystical themes. The tone reads as rich, imaginative, and slightly regal.
On the brightness scale, Plum scores roughly 296 out of 255, making it A bright shade that pops on dark canvases and works as a highlight, though it can feel harsh on large fills. It's also cool-leaning, so it will play nicely against warm oranges and yellows as a counterweight in most layouts. If you're trying to recreate this color in Figma, Photoshop, or a CSS variable, copy the hex directly; if you need screen-space matching, the RGB triplet above lands you on the same swatch.
The day before this puzzle was azure, and the day after was storm. Scanning a short run of recent answers is a useful way to see whether the curator has been leaning toward a particular palette that week, and it gives you a baseline for guessing future puzzles when a hex doesn't ring a bell. The full archive on this site indexes every Colordle back to launch, so you can flip through months at a time.
For working solvers, the Colordle helper on this site applies the same RGB distance math the official game uses, so you can plug a guess into it and get a near-match back without burning through your daily attempts.
