Notes on Afterglow
Where Afterglow comes from
Memory games are older than boards to play them on. The version most people meet first is Kim's game, named for the scene in Rudyard Kipling's 1901 novel in which a boy is shown a tray of jewels, the tray is covered, and he must recite what he saw; scouting organizations have used it as an observation drill ever since. The electronic era added its own landmark in 1978, when Milton Bradley's Simon turned four colored panels and a lengthening sequence into a living-room phenomenon — color as the thing remembered, pressure as the thing felt.
Afterglow narrows that whole lineage to a single, humbling question: not which colors did you see, but exactly what color was that? Perception research has an answer for why this is hard — color is among the first things the eye reads and the least faithful things memory keeps, and remembered colors tend to drift toward the vivid, typical version of their category. The teal you saw becomes, in recollection, a little more teal than it ever was. The game's name is honest about the experience: what you are rebuilding is not the color, but its afterglow.
How to get better at Afterglow
Say the color to yourself while it is still on screen. Two and a half seconds is enough to encode words as well as an image, and words survive the walk to the sliders far better than raw sensation. "Dusty teal, fairly bright, not quite gray" is a recipe you can still follow ten seconds later; a wordless impression is not.
Encode it as three numbers, because that is what the sliders will ask for. Learn the hue dial's landmarks — red at the start, yellow around 60, green near 120, cyan 180, blue 240, magenta 300 — and file the hue as a neighborhood between two of them. Then grade saturation and brightness in coarse thirds: soft, medium, or vivid; dark, mid, or light. Three rough coordinates beat one precise but decaying picture.
Set hue first, and fast. Hue is the coordinate memory loses soonest, and it costs the most points when it goes — a bright pink filed as bright blue is the difference between a near-perfect round and a shrug. Lock the hue neighborhood before you fuss over the other two sliders.
Correct for the drift. Because memory exaggerates toward the prototype, your instinct will run a touch too saturated and too clean. When you hesitate between two settings, take the slightly duller, slightly grayer one. Over five rounds this one habit is worth real points.
Keep the gap quiet. Rehearse your three-word recipe while you work the sliders instead of second-guessing the image, and do not let your eyes graze other strong colors — new color input overwrites old color memory with unreasonable speed.
A round in the life
The card fills with a muted violet — you murmur "purple-blue, soft, medium-light" before it vanishes. At the sliders you go to hue first: past blue, shy of magenta, around 275. Saturation gets the soft-third treatment, just over half. Brightness you remember as gentle, so you settle near 70, then remember the drift rule and pull saturation back one notch. Lock it in. The reveal sets your rebuild beside the truth: nearly twins, yours a whisper bluer. The round scores 9.2 of 10, the caption tips its cap, and four colors still stand between you and the day's 50.

From the rulebookHow to play Afterglow
Five colors, shown one at a time. Study each, then rebuild it from memory.
- A color fills the card for a few seconds, then it’s hidden. Hold it in your head.
- Rebuild it with the Hue, Saturation, and Brightness sliders, then lock it in.
- Each round scores up to 10 points for how close you land — five rounds make a possible 50.
- Same five colors for everyone, once a day.
Land a near-identical shade and the round scores high — the two colors above are almost the same green.
Misremember the hue and the score drops — pink versus blue is a long way apart.
