Which primary colour would be chosen as the base for a red rose?

Correct answer: Red

Red is the appropriate base colour for painting a red rose because it represents the flower’s main visible colour. Red is also one of the traditional primary colours, so it can be used directly rather than being produced by mixing other colours. Blue and yellow are primary colours but do not match the stated rose colour, while green is normally associated with the stem and leaves and is not a primary colour in this system. Lighter or darker red can add depth.
