Color Match — Find the Different Colour

What this level trains

Color Match is a small game many people have met before: one tile among a field of near-identical colour blocks has a subtly different shade, and you have to find it. It tests colour discrimination and scanning strategy far more than eyesight.

Difficulty tightens two things at once: the colour difference shrinks from obvious to barely visible, and the grid grows from a handful of tiles to more than a hundred. As the difference narrows, comparing neighbouring tiles side by side beats staring at each one.

Colour-vision differences, often called colour blindness, strongly affect this level, especially along the red-green axis. If you repeatedly fail a few levels while others feel normal, it may be individual colour discrimination rather than a lack of focus. That is a normal variation, not a failure of effort.

This level is still in development. The plan is eight levels, running from a 3×3 grid with an obvious difference up to a grid beyond 20×20 where the difference is only visible on close comparison, so no time thresholds are published yet. The interface and scoring will follow the same pattern as the other levels here.

How to play

1. Look at the whole fieldRelax your focus instead of locking onto one tile, so the average colour of the whole field enters your vision and the odd one stands out against it.
2. Find the odd oneThe different tile stands out through contrast, usually reading as darker, lighter, warmer or cooler than the tiles around it.
3. Tap itTapping the odd tile advances to the next level; a wrong tap simply gives feedback and you keep searching at your own pace.
4. Expect slowdowns laterAs the difference shrinks and the grid grows, the number of comparisons rises sharply, so do not expect to hold your opening pace on the harder levels.

The planned 8 difficulty levels

The plan is eight levels: levels 1 and 2 use a 3×3 to 4×4 grid with an obvious colour difference; levels 3 and 4 shrink the difference and grow the grid from 6×6 to 8×8; levels 5 and 6 move into two-digit grids; and levels 7 and 8 combine a very small difference with a large grid. This level has not launched yet, so no time thresholds are listed.

1. Level 13 × 3, a colour difference you spot at a glance
2. Level 24 × 4, still an obvious difference
3. Level 36 × 6, the difference gets smaller
4. Level 48 × 8, smaller again
5. Level 5Double-digit grids (10 × 10 and above)
6. Level 6Double-digit grids with an even subtler difference
7. Level 7Large grids with a minimal difference
8. Level 8The extreme tier: 20 × 20 and above, where you must compare block by block

Tips and common mistakes

• Squint at the whole fieldSquinting or stepping back lets your visual system average the colours, which often makes the odd tile pop out better than staring at it up close.
• Scan on a fixed pathSweep in a zigzag or in blocks instead of looking around randomly; a fixed path stops the same region from being skipped over twice.
• Do not stare at one spotColour vision adapts, so similar shades start to look identical if you stare too long. Glance away every few seconds and then come back.
• Turn off eye comfort modeNight mode, eye-comfort filters and auto-brightness all compress colour differences. Switch them off and keep screen brightness fixed for this level.

Frequently asked questions

Can people with colour blindness play this level?

Yes, but the low-contrast red-green levels will be very hard, while levels that rely mainly on brightness differences are less affected. If you suspect a colour-vision difference, a proper screening test such as the Ishihara plates is the sensible first step.

Does my monitor affect my score?

It does, and substantially. Colour gamut, temperature, brightness and any eye-comfort mode change the difference you actually see, so scores are not strictly comparable across different devices, and a great result on one monitor may not carry over to another.

What ability does this level train?

Sensitivity to subtle colour differences and a systematic visual scanning strategy. Those are the same two abilities that design, colour grading, printing and quality inspection rely on, so it is a quick way to warm up for that kind of work.

Is there a trick to get faster right away?

Squinting at the whole field, scanning along a fixed path, and looking away every few seconds usually deliver the biggest immediate speed-up. Try them in order and give each a few seconds before switching.

When will Color Match be available?

Color Match is still in development. Once it launches, this page will list the colour difference and grid size for each of the eight levels. Until then, the tips above are the best way to prepare, and the other attention levels make a good warm-up.
