Adding a light colour to a dark watercolour failed to create the desired light mixture. What is the correct order?

Correct answer: Add the dark colour gradually to the light mixture

Dark pigments often have strong tinting power, so a small quantity can noticeably lower the value of a light mixture. To retain control, first prepare the desired light colour with water, then add the dark pigment in tiny increments, testing after each addition. Adding all the light colour to a dark mixture may waste paint and still produce an uneven result. Equal quantities or black first do not reliably create the intended light tone. Option B is correct.
