Quick answer: Replace clashing pairs with a colorblind-safe palette (for example blue vs orange) and add a non-color marker so identity never depends on hue alone.
Red-vs-green team colors fail the most common color vision deficiencies. A colorblind-safe palette fixes it. Here is how.
How to fix it
1. Choose a safe color pair
Swap red/green for pairs that stay distinct across deficiencies, such as blue versus orange, and verify them with a colorblind simulator for all three types.
2. Offer palette presets
Provide selectable team-color palettes so players can pick the combination that reads best for their specific vision.
3. Add a redundant marker
Attach a shape or icon to friend and foe (a chevron for allies, a diamond for enemies) so identity survives even if colors still confuse.
Catching the ones you can't reproduce
The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.
Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.
This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
