Avoid color-only game instructions

The problem

A red-versus-green distinction fails for some users and in low-quality displays.

Practical procedure

Pair color with shapes, icons, labels or patterns that encode the same meaning.

Worked scenario

Represent a pickup with a star, the player with a diamond and the exit with a ring.

Acceptance check

Turn the screen grayscale and check whether every interactive tile remains distinguishable.

Apply the method

Use the related interactive tool to try the concept on an inspectable example. Record the starting assumptions and expected result before changing settings, then compare what the tool actually does. Where the result differs, keep the release marked experimental and document the discrepancy.
