Abstract	Colour priming is hypothesized to enhance memory and sustained attention through emotional arousal. This study conducted a direct replication of Dzulkifli and Mustafar (2013) in an Indian university population. Sixty undergraduate students (ages 18–25) were randomly assigned to three conditions: warm colour (red; n = 20), cool colour (blue; n = 20), or white control (n = 20). Participants completed a digit memory span task (MSPAN) and a sustained attention task (TOAV). Contrary to the original hypothesis, Kruskal-Wallis tests revealed no significant effects of colour priming on memory span, χ²(2) = 0.808, p = .668, η² = .02, or sustained attention reaction time, χ²(2) = 4.998, p = .082, η² = .053. Effect sizes were negligible. These null findings align with recent meta-analytic evidence of publication bias in colour psychology and suggest that colour priming effects may not generalize universally across populations. The replication contributes to cumulative psychological knowledge by testing boundary conditions and reducing publication bias.
