The Lüscher Color Test is a colour-preference personality test devised by the Swiss psychotherapist Max Lüscher and first presented in 1947. You rank eight colours from most to least liked, and Lüscher read that order as a portrait of your psychological state and needs. At its heart sit four 'basic colours', each standing for a basic need: dark blue for calm and contentment, blue-green for self-assertion and will, orange-red for drive and excitement, and bright yellow for hope and spontaneity. This asks which of the four draws you most. Widely used in popular and some clinical settings, the test is not backed by scientific evidence — independent research finds no construct validity and it appears on published lists of discredited assessments — so take it as a reflective prompt, not a measure.
A historic colour-preference test devised by the Swiss psychotherapist Max Lüscher (first presented in 1947; English edition translated and edited by Ian Scott, Random House, 1969). It has been used in clinical and commercial settings, but it is not supported by scientific evidence: independent studies have not confirmed its construct or predictive validity (Braün & Bonta, 1979), and it features among the techniques rated 'discredited' in an expert Delphi poll (Norcross, Koocher & Garofalo, 2006). Popular belief, not science — best treated as a reflective self-ID, not a measure. (Max Lüscher, The Lüscher Color Test (trans. & ed. Ian Scott), Random House, 1969; first presented 1947)
