Frequently asked questions

The test measures the Big Five with the public-domain IPIP-50 items and places your scores against a published online sample. That part has solid support. The colour mapping is a presentation choice, not a scientific claim: colours are labels for the traits, and the science page explains how strong each colour association is.

The full test has 10 items per trait, with reliability around .79 to .89 in this sample. That is decent for a short free test, but every score carries error, which is why the result shows an 80% likely range. The quick test has only 4 items per trait and is noticeably rougher. A single sitting also reflects your mood that day.

The full test uses all 50 IPIP Big Five markers and takes about 6 minutes. The quick test uses the 20 Mini-IPIP items and takes about 2 minutes. Both use the same colours and the same scoring maths; the quick version simply has fewer statements per trait, so its percentiles are coarse.

Colours are memorable and quick to share. The test does not claim that your favourite colour reveals your personality, and no question asks about colour. Each Big Five trait gets one colour so the result reads as a palette: yellow for Extraversion, green for Agreeableness, blue for Conscientiousness, red for Intensity, purple for Openness.

No. Scoring runs in your browser. Your answers and your result are saved only in your own browser storage so the test can resume and the result page can read your last palette. Nothing is sent to a server, and clearing your browser data removes everything. The privacy page has the details.

The likely range is an 80% interval around your percentile, based on the reliability of the scale. A wide range means the test is less certain about your exact position. If the range crosses the middle, treat the high or low label as gentle rather than firm.

Yes. There is no account, no email, no payment and no advertising on the site. The IPIP items are public domain, which is part of why the test can stay free and open.

You can use it for your own reflection or as a conversation starter if you choose. Do not use it as evidence about a colleague, and do not use it for hiring, promotion or team decisions about other people. It is a self-report snapshot, not an assessment of anyone else.

The leading trait usually stays similar across years, but scores move with life events, mood and age. Retake the test after a few months and compare the overall shape rather than a single percentile. The test keeps no history on a server, so comparisons come from your own memory or saved links.

Yes. The result page builds a 1080x1350 palette card in your browser and can share it through your device. The share link carries five percentiles in the hash and nothing else: no name, no answers, no account. Anyone with the link sees a palette, not your data.
