Which activity can best test the identification of primary colours?

Correct answer: Separating red, yellow and blue

A sound assessment activity should require learners to recognise the target colours directly. Separating red, yellow and blue tests whether students can identify the three traditional primary colours, so option A is correct. Turning every colour black removes the evidence of colour recognition, while pencil writing and paper folding assess unrelated skills. Naming or labelling the separated colours could make this activity even more informative.
