Is blue dye more effective than red dye on a whiteflower?

The effectiveness of blue dye compared to red dye on a white flower depends on the specific plant species and the type of dye used. Generally, blue dye may appear more vibrant against a white flower due to the contrast, while red dye could also produce a striking effect. However, the absorption and appearance can vary based on the flower's uptake of the dye and the dye's properties. Ultimately, the perceived effectiveness is subjective and related to aesthetic preferences.
