SPECTRA - Visual Recall Game

Now free, with 150 levels in every game and a leaderboard that ranks the longest streak, not the longest grind. One-time Pro removes every ad.

How accurately do you actually see color?

Spectra shows you a color, takes it away, and asks you to rebuild it from memory on three sliders. Your answer is scored against the original with CIEDE2000, the color difference formula used in print and manufacturing, so "close enough" stops working as the levels climb.

KING'S EYE

The endless mode. One color at a time, no clock on your answer, and a streak that counts every color you got right in a row. The minimum score climbs with the streak: 5.5 out of 10 for your first five colors, 9.2 once you pass 70. Miss once and a short video buys you one retry. Miss again and the streak resets to zero.

Your rank comes from the best streak you have ever reached. Five gets you Knight, 16 makes you a Baron, and King starts at 71. The global leaderboard ranks by longest streak, so one clean run beats hours of grinding.

FOUR MORE GAMES, 150 LEVELS EACH

Odd One Out. One tile in the grid sits at a slightly different shade. Find it before the timer ends. The grid grows from 4x4 to 6x6 while the time you get per tile keeps shrinking.

Color Sequence. Colors flash in order, then you tap them back in that order. The sequence runs longer and the palette gets more crowded.

Warm or Cool. Look at a color, then at the next one, and decide whether it is warmer or cooler. The hue shift between the two narrows to a few degrees.

Find the Original. Memorize a color, then pick it out of a grid of near identical neighbors. The grid goes from eight options to twelve.

Every level is fixed. Level 84 is the same puzzle for you as for everyone else, today and next month, so a level you cleared stays cleared. The first fifty are chapter one, and finishing it opens the next fifty.

FREE TO PLAY

Nothing is locked behind a paywall. Free play is funded by one full-screen ad after every eighth level you clear, plus the optional video on the King's Eye retry. The one-time Pro purchase removes both for good and makes the retry free and unlimited. There is no subscription.

You do not need an account or an email address. Your progress and your leaderboard entry are tied to an anonymous ID.
