How to read a color vision test result (direct answer)
An online Ishihara-style report hints whether you struggle with certain color combinations on this device - it is not a hospital diagnosis. Watch: (1) overall accuracy; (2) whether red-green items fail in a pattern; (3) whether traffic lights, cable colors, or charts already feel hard.
If red-green items fail repeatedly or daily tasks are affected, book an eye exam. If results look normal but you are unsure, retest on another device with night mode off.
High accuracy
Usually suggests lower chance of clear deficiency, but screens still affect outcomes; use clinic checks for important decisions.
Systematic red-green misses
Even with a decent total score, this can suggest Protan / Deutan risk - prioritize a formal color vision exam.
Only blue-yellow difficulty
Less common. Rule out display tint and medical/medication factors; do not self-diagnose.
Different results on another phone
Common. Gamut, white point, and brightness change plate visibility. Note device model and night-mode settings when describing results to a doctor.
Next steps
What to do after you get a reference result
1. Compare with daily life
Check traffic lights, cable colors, spreadsheets, and map legends. Real-world difficulty matters more than one web test.
2. Decide on a clinic check
If you need a driving license, a color-critical job, or repeat abnormal self-tests, book an eye exam early.
3. Improve digital accessibility
Even with typical color vision, enable high contrast and shape cues so interfaces do not rely on color alone.
Driving and jobs: what this report can and cannot prove
A reference report can help you anticipate risk, reduce anxiety, and prepare questions for a clinician. It cannot serve as a legal color vision certificate for licensing offices, clinics, or employers.
Common misconceptions
- "100% online means I will pass the clinic" - not necessarily; lighting and printed plates differ.
- "A poor online score means no hope" - also not necessarily; severity and local standards vary.
- "One test is enough" - retest with night mode off and note device differences.

FAQ
Result interpretation FAQ
What accuracy counts as normal?
Online screening has no universal pass mark. Higher accuracy with stable red-green answers usually suggests lower risk; patterned red-green errors deserve attention. Clinic exams are definitive.
What do L / M / S cone notes mean?
They refer to long (red), medium (green), and short (blue) channels as educational labels. Values estimated from answer patterns are not lab measurements.
Do I need a hospital visit after an abnormal self-test?
If results suggest risk or daily color tasks are hard, see an eye doctor - especially before driving or color-critical jobs.
Why do results change on another phone?
Normal. Gamut, white point, and brightness change plate visibility. Use your main device as a life reference and clinic testing as the final word.
