What can be a common reason for failing to obtain a clean violet?

Answer and explanation

Correct answer: A trace of yellow in the red or blue

The governing concept is the effect of an unwanted third primary in a secondary-colour mixture. Violet is formed from red and blue, so clean pigments and tools are needed. If yellow contaminates either colour, it combines with the mixture and reduces the clarity of violet, often making it dull or brownish. Thus option A is correct. Clean colours, a clean palette, and a suitable ratio are helpful practices, so options B, C, and D do not explain the failure.
